Some commonly used values.

Types

type Int

type Int int64

Int holds a fixed-point value that contains up to 1 decimal places. Values are truncated, not rounded. Values can be added and subtracted directly. For multiplication and division, the provided Mul() and Div() methods should be used.

func FromFloat32

func FromFloat32(value float32) Int

FromFloat32 creates a new value from a float32.

func FromFloat64

func FromFloat64(value float64) Int

FromFloat64 creates a new value from a float64.

func FromInt

func FromInt(value int) Int

FromInt creates a new value from an int.

func FromInt64

func FromInt64(value int64) Int

FromInt64 creates a new value from an int64.

func FromString

func FromString(str string) (Int, error)

FromString creates a new value from a string.

func FromStringForced

func FromStringForced(str string) Int

FromStringForced creates a new value from a string.

func (Int) Abs

func (f Int) Abs() Int

Abs returns the absolute value of this value.

func (Int) AsFloat32

func (f Int) AsFloat32() float32

AsFloat32 returns the floating-point equivalent to this value.

func (Int) AsFloat64

func (f Int) AsFloat64() float64

AsFloat64 returns the floating-point equivalent to this value.

func (Int) AsInt

func (f Int) AsInt() int

AsInt returns the truncated equivalent integer to this value.

func (Int) AsInt64

func (f Int) AsInt64() int64

AsInt64 returns the truncated equivalent integer to this value.

func (Int) Ceil

func (f Int) Ceil() Int

Ceil returns the value rounded up to the nearest whole number.

func (Int) Comma

func (f Int) Comma() string

Comma returns the same as String(), but with commas for values of 1000 and greater.

func (Int) CommaWithSign

func (f Int) CommaWithSign() string

CommaWithSign returns the same as Comma(), but prefixes the value with a '+' if it is positive

func (Int) Dec

func (f Int) Dec() Int

Dec returns the value decremented by 1.

func (Int) Div

func (f Int) Div(value Int) Int

Div divides this value by the passed-in value, returning a new value.

func (Int) Float32

func (f Int) Float32() (float32, error)

Float32 is the same as AsFloat32(), except that it returns an error if the value cannot be represented exactly with a float32.

func (Int) Float64

func (f Int) Float64() (float64, error)

Float64 is the same as AsFloat64(), except that it returns an error if the value cannot be represented exactly with a float64.
