Function `f64_nearest`

#[must_use = "method returns a new number and does not mutate the original value"]
pub fn f64_nearest(a: f64) -> f64

Generates the f64.nearest instruction, roundinging to the nearest integer. Rounds half-way cases to the number with an even least significant digit.

This method is useful when targeting no_std and is equivalent to std::f64::round_ties_even().
