Functions

func AbsInt32

func AbsInt32(v int32) int32

AbsInt32 abs(v)

ignore int exceeds limit error, abs(MinInt32) == MaxInt32

func AbsInt64

func AbsInt64(v int64) int64

AbsInt64 abs(v)

ignore int exceeds limit error, abs(MinInt64) == MaxInt64

func Bytes2Str

func Bytes2Str(b []byte) string

Bytes2Str unsafe convert bytes to str

func HumanReadableByteCount

func HumanReadableByteCount(bytes int64, si bool) (ret string)

HumanReadableByteCount convert bytes to human readable string

Args:

• bytes:
• si: `si ? 1024 : 1000`

Example:

`HumanReadableByteCount(1005, false) -> "1.01KB"`
