Functions

func AllowImpreciseConversion

func AllowImpreciseConversion(b bool)

func AllowOverflow

func AllowOverflow(b bool)

func Float64

func Float64(v interface{}) (float64, error)

Float64 converts a numeric type to a float64, if possible. Note for very large integers, this may lose information!

func Int64

func Int64(v interface{}) (int64, error)

Int64 converts an integer type to an int64, if possible. Note that for very large unsigned ints, this may give an incorrect result!

func String

func String(v interface{}) (string, bool)

String converts strings, []bytes, and []runes to strings

func WarnOnImpreciseConversion

func WarnOnImpreciseConversion(b bool)
