Trait Float 

pub trait Float {
    // Required methods
    fn round_dp(self, decimal_places: u32) -> Self;
    fn ceil_dp(self, decimal_places: u32) -> Self;
    fn floor_dp(self, decimal_places: u32) -> Self;
}

Required Methods

fn round_dp(self, decimal_places: u32) -> Self

Rounds the number to the given number of decimal places

Examples

use common_math::rounding::*;

assert_eq!(123.456_f64.round_dp(2), 123.46_f64);
assert_eq!(123.456_f64.round_dp(0), 123_f64);
assert_eq!(123.456_f32.round_dp(2), 123.46_f32);

fn ceil_dp(self, decimal_places: u32) -> Self

Rounds the number up to the given number of decimal places

Examples

use common_math::rounding::*;

assert_eq!(123.454_f64.ceil_dp(2), 123.46_f64);
assert_eq!(123.456_f64.ceil_dp(0), 124_f64);
assert_eq!(123.454_f32.ceil_dp(2), 123.46_f32);

fn floor_dp(self, decimal_places: u32) -> Self

Rounds the number down to the given number of decimal places

Examples

use common_math::rounding::*;

assert_eq!(123.456_f64.floor_dp(2), 123.45_f64);
assert_eq!(123.456_f64.floor_dp(0), 123_f64);
assert_eq!(123.454_f32.floor_dp(2), 123.454_f32);

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.
