fflib/v1/decimal.go:317–326

Round a to nd digits (or fewer). If nd is zero, it means we're rounding just to the left of the digits, as in 0.09 -> 0.1.

(nd int)

// just to the left of the digits, as in
// 0.09 -> 0.1.
func (a *decimal) Round(nd int) {
	if nd < 0 || nd >= a.nd {
		return
	}
	if shouldRoundUp(a, nd) {
		a.RoundUp(nd)
	} else {
		a.RoundDown(nd)
	}
}

// Round a down to nd digits (or fewer).
func (a *decimal) RoundDown(nd int) {
