fn

pub const fn Abs<T>(Value: T) -> T where T: Numeric, Copyable

Returns an exact nonnegative magnitude when the destination can represent it. T: Copyable supported numeric representation. Value: Numeric input; no storage is retained. Return: Absolute value; floating negative zero becomes positive zero and NaN propagates. Warning: Signed minimum fatal-traps because its positive magnitude is unrepresentable.
