Trait fpdec::Quantize

pub trait Quantize<Rhs = Self> {
    type Output;

    fn quantize(self, quant: Rhs) -> Self::Output;
}

Rounding a number to the nearest integer multiple of a given quantum.

Required Associated Types

type Output

The resulting type after applying quantize.

Required Methods

fn quantize(self, quant: Rhs) -> Self::Output

Returns an instance of Self::Output with its value set to the integer multiple of quant nearest to self, according to the current RoundingMode.

Panics

Panics if quant equals zero or the resulting value can not be represented by Self::Output!

Examples

let i = -322_i32;
let q = 3_i32;
let r = i.quantize(q);
assert_eq!(r.to_string(), "-321");
let d = Dec!(28.27093);
let q = 5_u32;
let r = d.quantize(q);
assert_eq!(r.to_string(), "30");
let q = Dec!(0.05);
let r = d.quantize(q);
assert_eq!(r.to_string(), "28.25");
