Required Methods§

Source

fn round(self, n_frac_digits: i8) -> Self

Returns a new Self instance with its value rounded to n_frac_digits fractional digits according to the current RoundingMode.

Source

fn checked_round(self, n_frac_digits: i8) -> Option<Self>

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
