Expand description

This trait provides checked conversions from fixed-point numbers.

This trait is implemented for conversions between integer primitives, floating-point primitives and fixed-point numbers.

Examples

use fixed::traits::FromFixed;
use fixed::types::U8F8;
// 0x87.65
let f = U8F8::from_bits(0x8765);
assert_eq!(f32::from_fixed(f), f32::from(0x8765u16) / 256.0);
assert_eq!(i32::checked_from_fixed(f), Some(0x87));
assert_eq!(u8::saturating_from_fixed(f), 0x87);
// no fit
assert_eq!(i8::checked_from_fixed(f), None);
assert_eq!(i8::saturating_from_fixed(f), i8::MAX);
assert_eq!(i8::wrapping_from_fixed(f), 0x87u8 as i8);
assert_eq!(i8::overflowing_from_fixed(f), (0x87u8 as i8, true));

Required methods

fn from_fixed<F: Fixed>(src: F) -> Self[src]

Expand description

Converts from a fixed-point number.

Any extra fractional bits are discarded, which rounds towards −∞.

Panics

When debug assertions are enabled, panics if the value does not fit. When debug assertions are not enabled, the wrapped value can be returned, but it is not considered a breaking change if in the future it panics; if wrapping is required use wrapping_from_fixed instead.

impl FromFixed for F128Bits[src]

fn from_fixed<F: Fixed>(src: F) -> Self[src]

Converts a fixed-point number to a floating-point number.

Panics

When debug assertions are enabled, panics if the value does not fit. When debug assertions are not enabled, the wrapped value can be returned, but it is not considered a breaking change if in the future it panics; if wrapping is required use wrapping_from_fixed instead.

fn checked_from_fixed<F: Fixed>(src: F) -> Option<Self>[src]

Converts a fixed-point number to a floating-point number if it fits, otherwise returns None.
