Number.toLongString() Method For Extremely Large Values

The standard Number.toString() method returns values in scientific notation once they exceed 10^20. In many cases, this is not an expected or desired result.

The toLongString() method provides a solution by always returning a literal numeric value regardless of the number's size. However, the value returned will not be accurate beyond the first [log base (radix) of (10^15)] digits.

radix: Optional. A number between 2 and 36, inclusive.Number.prototype.toLongString = function(){
var radix, n = this, d, t = '', p = ''
if(arguments.length>0 && typeof(arguments[0])=='number'){
radix = Math.round(arguments[0]);
if(radix<2) radix = 2;
if(radix>36) radix = 36;
} else {
radix = 10;
}
if(n < 0){
n *= -1;
p = '-'
}
while(n > radix){
d = n % radix;
n = (n-d)/radix;
t = d.toString(radix) + t;
}
return p + n.toString(radix) + t;
}
