Number.isFloat(3.14); // true
Number.isFloat(0.5); // true
Number.isFloat(42); // false
Number.isFloat(NaN); // false
Number.isFloat(Infinity); // false

data-last

import { Number } from "@monstermann/number";

pipe(3.14, Number.isFloat()); // true
pipe(0.5, Number.isFloat()); // true
pipe(42, Number.isFloat()); // false
pipe(NaN, Number.isFloat()); // false
pipe(Infinity, Number.isFloat()); // false
