将大数转换为字符串而不使用科学计数法

Question

例如：Number.MAX_VALUE.toString() 是 "1.7976931348623157e+308"

我希望没有e+308，怎样实现呢？

你可以这样做：

var n = Number.MAX_VALUE.toString();
var parts = n.split("e+");
var first = parts[0].replace('.', "");
var zeroes = parseInt(parts[1], 10) - (first.length - 1);
for(var i = 0; i < zeroes; i++){ first += "0"; }
// => first === "179769313486231570000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000"
