Benchmark: controllo velocità conversione byte

Script Preparation code:

let x = 132

Tests:

prova 1
let s = (x >>> 0).toString(2); if ( x > 0 && s.substr(3,1) == '0' && s.substr(4,1) == '0' && s.substr(7,1) == '0' ) { return s; }
prova 2
if ( x > 0 && (x & 8) == 0 && (x & 16) == 0 && (x & 128) == 0 ){ return (x >>> 0).toString(2); }
prova 3
if ( x > 0 && (x & Math.pow(2,3) == 0 && (x & Math.pow(2,4)) == 0 && (x & Math.pow(2,7)) == 0 ){ return (x >>> 0).toString(2); }
