Functions ¶
func Add ¶
func Add(res, x, y *apd.Decimal) error
Add adds x and y and stores the result in res with arbitrary precision or returns an error.
func DecimalString ¶
func DecimalString(x *apd.Decimal) string
DecimalString prints x as a floating point string.
func NumDecimalPlaces ¶
func NumDecimalPlaces(x *apd.Decimal) uint32
NumDecimalPlaces returns the number of decimal places in x.
func ParseNonNegativeDecimal ¶
ParseNonNegativeDecimal parses a non-negative decimal or returns an error.
func ParseNonNegativeFixedDecimal ¶
ParseNonNegativeDecimal parses a non-negative decimal with a fixed maxDecimalPlaces or returns an error.
func ParsePositiveDecimal ¶
ParsePositiveDecimal parses a positive decimal or returns an error.
func ParsePositiveFixedDecimal ¶
ParsePositiveFixedDecimal parses a positive decimal with a fixed maxDecimalPlaces or returns an error.
