round-to

Round floating point to integer.

Usage

You can round to i32 and i64 explicitly:

use round_to::*;

assert_eq!(0.4.round_to_i32(), 0);
assert_eq!(0.6.round_to_i64(), 1);

or implicitly to i8, i16, i32, i64, i128, isize, u8, u16, u32, u64, u128, or usize:

use round_to::*;

let a: i8 = 0.4.round_to();
assert_eq!(a, 0);

using these modes:

use round_to::*;

assert_eq!(0.5.round_to_i32(), 0);
assert_eq!(0.5.floor_to_i32(), 0);
assert_eq!(0.5.ceil_to_i32(), 1);

Implementation

Rounding is implemented using round_ties_even. Floor and ceil use floor and ceil. Values are then converted to target integer type using as.
