const ( MaxFractionDigits = 30 DivIncreasePrecision = 4 )
DivisionPrecision is the number of decimal places in the result when it doesn't divide exactly.
Example:
d1 := decimal.NewFromFloat(2).Div(decimal.NewFromFloat(3) d1.String() // output: "0.6667" d2 := decimal.NewFromFloat(2).Div(decimal.NewFromFloat(30000) d2.String() // output: "0.0001" d3 := decimal.NewFromFloat(20000).Div(decimal.NewFromFloat(3) d3.String() // output: "6666.6666666666666667" decimal.DivisionPrecision = 3 d4 := decimal.NewFromFloat(2).Div(decimal.NewFromFloat(3) d4.String() // output: "0.6667"

Types ¶
type Decimal ¶
type Decimal struct {
// contains filtered or unexported fields
}
Decimal represents a fixed-point decimal. It is immutable. number = value * 10 ^ exp
func ConvertToDecimal ¶
ConvertToDecimal converts interface to decimal.
func NewDecimalFromFloat ¶
NewDecimalFromFloat converts a float64 to Decimal.
Example:
NewDecimalFromFloat(123.45678901234567).String() // output: "123.4567890123456" NewDecimalFromFloat(.00000000000000001).String() // output: "0.00000000000000001"
NOTE: this will panic on NaN, +/-inf.
func NewDecimalFromFloatWithExponent ¶
NewDecimalFromFloatWithExponent converts a float64 to Decimal, with an arbitrary number of fractional digits.
Example:
NewDecimalFromFloatWithExponent(123.456, -2).String() // output: "123.46"
func NewDecimalFromInt ¶
NewDecimalFromInt returns a new fixed-point decimal, value * 10 ^ exp.
func NewDecimalFromUint ¶
NewDecimalFromUint returns a new fixed-point decimal, value * 10 ^ exp.
func ParseDecimal ¶
ParseDecimal returns a new Decimal from a string representation.
Example:
d, err := ParseDecimal("-123.45")
d2, err := ParseDecimal(".0001")
func (Decimal) Cmp ¶
Cmp compares the numbers represented by d and d2, and returns:
-1 if d < d2 0 if d == d2 +1 if d > d2
func (Decimal) Div ¶
Div returns d / d2. If it doesn't divide exactly, the result will have DivisionPrecision digits after the decimal point.
func (Decimal) Float64 ¶
Float64 returns the nearest float64 value for d and a bool indicating whether f represents d exactly. For more details, see the documentation for big.Rat.Float64.
func (Decimal) FracDigits ¶
FracDigits returns the number of fractional digits of the decimal.
func (Decimal) MarshalJSON ¶
MarshalJSON implements the json.Marshaler interface.
func (Decimal) MarshalText ¶
MarshalText implements the encoding.TextMarshaler interface for XML serialization.
func (Decimal) Round ¶
Round rounds the decimal to places decimal places. If places < 0, it will round the integer part to the nearest 10^(-places).
Example:
NewFromFloat(5.45).Round(1).String() // output: "5.5" NewFromFloat(545).Round(-1).String() // output: "550"
func (Decimal) String ¶
String returns the string representation of the decimal with the fixed point.
Example:
d := New(-12345, -3) println(d.String())
Output:
-12.345
func (Decimal) StringFixed ¶
StringFixed returns a rounded fixed-point string with places digits after the decimal point.
Example:
NewFromFloat(0).StringFixed(2) // output: "0.00" NewFromFloat(0).StringFixed(0) // output: "0" NewFromFloat(5.45).StringFixed(0) // output: "5" NewFromFloat(5.45).StringFixed(1) // output: "5.5" NewFromFloat(5.45).StringFixed(2) // output: "5.45" NewFromFloat(5.45).StringFixed(3) // output: "5.450" NewFromFloat(545).StringFixed(-1) // output: "550"
func (Decimal) StringScaled ¶
StringScaled first scales the decimal then calls .String() on it. NOTE: buggy, unintuitive, and DEPRECATED! Use StringFixed instead.
func (Decimal) Truncate ¶
Truncate truncates off digits from the number, without rounding.
NOTE: precision is the last digit that will not be truncated (must be >= 0).
Example:
decimal.NewFromString("123.456").Truncate(2).String() // "123.45"
func (*Decimal) UnmarshalJSON ¶
UnmarshalJSON implements the json.Unmarshaler interface.
func (*Decimal) UnmarshalText ¶
UnmarshalText implements the encoding.TextUnmarshaler interface for XML deserialization.
type Duration ¶
type Duration struct {
time.Duration
// Fsp is short for Fractional Seconds Precision.
// See http://dev.mysql.com/doc/refman/5.7/en/fractional-seconds.html
Fsp int
}
Duration is the type for MySQL time type.
func ParseDuration ¶
ParseDuration parses the time form a formatted string with a fractional seconds part, returns the duration type Time value. See: http://dev.mysql.com/doc/refman/5.7/en/fractional-seconds.html
func (Duration) Compare ¶
Compare returns an integer comparing the Duration instant t to o. If d is after o, return 1, equal o, return 0, before o, return -1.
func (Duration) CompareString ¶
CompareString is like Compare, but parses str to Duration then compares.
func (Duration) ConvertToTime ¶
ConvertToTime converts duration to Time. Tp is TypeDatetime, TypeTimestamp and TypeDate.
func (Duration) MicroSecond ¶
MicroSecond returns current microsecond. e.g, hour("11:11:11.11") -> 110000
func (Duration) RoundFrac ¶
RoundFrac rounds fractional seconds precision with new fsp and returns a new one. We will use the “round half up” rule, e.g, >= 0.5 -> 1, < 0.5 -> 0, so 10:10:10.999999 round 0 -> 10:10:11 and 10:10:10.000000 round 0 -> 10:10:10
type SQLError ¶
SQLError records an error information, from executing SQL.
func NewDefaultError ¶
NewDefaultError generates a SQL error, with an error code and extra arguments for a message format specifier.
type Time ¶
type Time struct {
time.Time
Type uint8
// Fsp is short for Fractional Seconds Precision.
// See http://dev.mysql.com/doc/refman/5.7/en/fractional-seconds.html
Fsp int
}
Time is the struct for handling datetime, timestamp and date. TODO: check if need a NewTime function to set Fsp default value?
func ParseDateFromNum ¶
ParseDateFromNum is a helper function wrapping ParseTimeFromNum with date type.
func ParseDatetime ¶
ParseDatetime is a helper function wrapping ParseTime with datetime type and default fsp.
func ParseDatetimeFromNum ¶
ParseDatetimeFromNum is a helper function wrapping ParseTimeFromNum with datetime type and default fsp.
func ParseTime ¶
ParseTime parses a formatted string with type tp and specific fsp. Type is TypeDatetime, TypeTimestamp and TypeDate. Fsp is in range [0, 6]. MySQL supports many valid datatime format, but still has some limitation. If delimiter exists, the date part and time part is seperated by a space or T, other punctuation character can be used as the delimiter between date parts or time parts. If no delimiter, the format must be YYYYMMDDHHMMSS or YYMMDDHHMMSS If we have fractional seconds part, we must use decimal points as the delimiter. The valid datetime range is from '1000-01-01 00:00:00.000000' to '9999-12-31 23:59:59.999999'. The valid timestamp range is from '1970-01-01 00:00:01.000000' to '2038-01-19 03:14:07.999999'. The valid date range is from '1000-01-01' to '9999-12-31'
func ParseTimeFromNum ¶
ParseTimeFromNum parses a formatted int64, returns the value which type is tp.
func ParseTimestamp ¶
ParseTimestamp is a helper function wrapping ParseTime with timestamp type and default fsp.
func ParseTimestampFromNum ¶
ParseTimestampFromNum is a helper function wrapping ParseTimeFromNum with timestamp type and default fsp.
func (Time) Compare ¶
Compare returns an integer comparing the time instant t to o. If t is after o, return 1, equal o, return 0, before o, return -1.
func (Time) CompareString ¶
CompareString is like Compare, but parses string to Time then compares.
func (Time) ConvertToDuration ¶
ConvertToDuration converts mysql datetime, timestamp and date to mysql time type. e.g, 2012-12-12T10:10:10 -> 10:10:10 2012-12-12 -> 0
func (Time) RoundFrac ¶
RoundFrac rounds fractional seconds precision with new fsp and returns a new one. We will use the “round half up” rule, e.g, >= 0.5 -> 1, < 0.5 -> 0, so 2011:11:11 10:10:10.888888 round 0 -> 2011:11:11 10:10:11 and 2011:11:11 10:10:10.111111 round 0 -> 2011:11:11 10:10:10
func (Time) ToNumber ¶
ToNumber returns a formatted number. e.g, 2012-12-12T10:10:10 -> 20121212101010 2012-12-12T10:10:10.123456 -> 20121212101010.123456
