Crate assert_eq_float

assert-eq-float

This crate provides the assert_eq_float! macro that supports floats.

Examples

use assert_eq_float::assert_eq_float;

assert_eq_float!(1.1 + 0.1, 1.2); // error = 0.0000000000000021316282072803005
assert_eq_float!(1e100 + 2e100, 3e100); // error = 53290705182007510000000000000000000000000000000000000000000000000000000000000000000000

The default margin of error is dynamically computed by properties of IEEE 754 floating point numbers. You don’t need to worry about it if you just want to check two float values are equal.

Macros

• assert_eq_float
  Asserts that two float expressions are (approximately) equal to each other.
