                    replacingInfinity(with:)

Returns replacement if self.isInfinite is true, or self if self is finite.

Declaration

Swift

public func replacingInfinity(with replacement: Self) -> Self


                    
                    
                    round(_:by:)

Rounds this value to the specified scale, where the scale is the number of rounding stops per integer.

A rounding scale of 1.0 is standard integer rounding. A rounding scale of 2.0 rounds to halves (0, 0.5, 1.0, 1.5, 2.0, 2.5., …). A rounding scale of 3.0 rounds to thirds (0, 1/3, 2/3, 1.0, 4/3, 5/3, 2.0, …).

Declaration

Swift

public mutating func round(_ rule: FloatingPointRoundingRule, by scale: Self)

Parameters

`rule`	the rounding rule
`scale`	the rounding scale
