Method RoundFloor

decimal.go:1580–1595

RoundFloor rounds the decimal towards -infinity. Example: NewFromFloat(545).RoundFloor(-2).String() // output: "500" NewFromFloat(-500).RoundFloor(-2).String() // output: "-500" NewFromFloat(1.1001).RoundFloor(2).String() // output: "1.1" NewFromFloat(-1.454).RoundFloor(1).String() // outp

(places int32)

//	NewFromFloat(1.1001).RoundFloor(2).String() // output: "1.1"
//	NewFromFloat(-1.454).RoundFloor(1).String() // output: "-1.5"
func (d Decimal) RoundFloor(places int32) Decimal {
	if d.exp >= -places {
		return d
	}

	rescaled := d.rescale(-places)
	if d.Equal(rescaled) {
		return d
	}

	if d.value.Sign() < 0 {
		rescaled.value.Sub(rescaled.value, oneInt)
	}

	return rescaled
}

// RoundUp rounds the decimal away from zero.
