Function datafusion_physical_expr::intervals::rounding::next_up

pub fn next_up<F: FloatBits + Copy>(float: F) -> F

Returns the next representable floating-point value greater than the input value.

This function takes a floating-point value that implements the FloatBits trait, calculates the next representable value greater than the input, and returns it.

If the input value is NaN or positive infinity, the function returns the input value.

Examples

use datafusion_physical_expr::intervals::rounding::next_up;

let f: f32 = 1.0;
let next_f = next_up(f);
assert_eq!(next_f, 1.0000001);
