Functions

func AlignDown

func AlignDown[T UI](n, alignment T) T

func AlignUp

func AlignUp[T UI](n, alignment T) T

func ParseFloat

func ParseFloat[T Float](i any) (T, error)

func ParseInteger

func ParseInteger[T Integer](i any) (T, error)

func ParseIntegers

func ParseIntegers[T Integer, V any](arr []V) (ret []T, err error)

func ParseNumber

func ParseNumber(i any) (_ uint64, isFloat bool, _ error)

ParseNumber converts i to uint64 (with sign kept)

if i is a float number (indicated by return value isFloat), return IEEE 754 bits of i

func ParseString

func ParseString(str string, assumeFloat bool) (uint64, bool, error)

ParseString parses a number in string, it may be a float

func ParstFloats

func ParstFloats[T Float, V any](arr []V) (ret []T, err error)
