nv-string-pos-int-lt1e21 v1.0.2

nv-string-pos-int-lt1e21

• same as Number.toString()
• but only work WHEN number is integer AND number >0 AND number < 1e21
• slightly faster than built-in .toString()

install

• npm install nv-string-pos-int-lt1e21

usage

  const {pos_i2s_if_gt0_and_lt_1e21 }   = require("nv-string-pos-int-lt1e21");

example

	const rand_int = ()=>require("nv-random-number").int(1,2**53);
	  

	// random samples for test
	const narr = [];
	const sarr = [];
	for(let i=0;i<1000000;++i) {
	    let int = rand_int();
	    let s   = int.toString();
	    narr.push(int);
	    sarr.push(s);
	}

	const {pos_i2s_if_gt0_and_lt_1e21} = require("../index");
