Types

type Money

type Money int64

Money is a sum of money multiplied by precision (100). It can be negative Money is marshalled without multiplication:

• FromInt(15) -> 15
• FromFloat(15.07) -> 15.07
• FromFloat(15.073) -> 15.07
• FromFloat(15.078) -> 15.07

func FromFloat

func FromFloat(m float64) Money

FromFloat converts float64 to Money
