random floats from zero-to-one using crypto.getRandomValues()

cryptoFloats.js

const crandomVal = () => (crypto.getRandomValues(new Uint32Array(1))[0] / (2 ** 32)) ;

const crandomInt = (a=1) => ~~((crypto.getRandomValues(new Uint32Array(1))[0] / (2 ** 32)) * a);

const crandomArr = (a=1, b=1) => [...crypto.getRandomValues(new Uint32Array(a))].map(v => (v / 2**32) * b);

const crandomIntArr = (a=1, b=1) => [...crypto.getRandomValues(new Uint32Array(a))].map(v => ~~((v / 2**32) * b));

this uses the crypto method of generating random values to return floating point values between zero and one; it functions like Math.random() but uses the crypto's values
