Function perimeter 

pub fn perimeter(x: f64, y: f64) -> f64

perimeter(x, y)

Geometry Function

The perimeter function calculates the total length of a rectangle’s boundaries, given its width and height, returning the result as a floating-point number.

Examples

use mathlab::math::{perimeter, INF_F64 as inf};
assert_eq!(perimeter(0.0 , 0.0), 0.0);
assert_eq!(perimeter(0.0 , 1.0), 2.0);
assert_eq!(perimeter(1.0 , 0.0), 2.0);
assert_eq!(perimeter(1.0 , 1.0), 4.0);
assert_eq!(perimeter(2.0 , 1.0), 6.0);
assert_eq!(perimeter(inf , 1.0), inf);
