將大數字轉換爲沒有科學記數法的字符串

Question

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

我希望沒有e+308，怎麼做到這一點？

Answer 1

你可以這樣做：

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"
