a rust macro for asserting 2 numbers are approximately equal
This crate exports a macro for asserting that two numbers are approximately equal (
1.0e-6, by default) to each other.
On panic, this macro will print the values of the expressions with their
debug representations. You can optionally add an optional diff value. If you
don't supply a diff value as an argument,
1.0e-6 is the default used.
To use this crate, add
assert_approx_eq as a dependency of your Rust project.
Then, you can use the macro as follows:
use assert_approx_eq::assert_approx_eq; let a = 3f64; let b = 4f64; assert_approx_eq!(a, b); // panics assert_approx_eq!(a, b, 2f64); //does not panic assert_approx_eq!(a, b, 1e-3f64); // panics
