Example: 7895431531579543114684 = ok
6548.65154684897456167489156 = (if spaces = 10, number should be 6548.6515468490)
That works. But, if only if the number has decimal places that surpass the give allowed amount.
if i just use a whole number, nothing happens. no value is returned or anything
if the allowed spaces = 5, but the number has 4 numbers past the decimal point, still nothing happens.
Code: Select all
function NumRound (number,spaces) {
// if the number is a whole number, simply return that number
if (number.split('.')){
var num = number.split('.');
} else {
return number;
}
// check of the length of the decimal places is longer than allowed
if (num[1].length > spaces) {
var count = 0;
var decCount = 1;
while (count < spaces) {
decCount *= 10;
count++;
}
// makes the number of spaces past decimal point become part of whole number
number *= decCount;
// round it to remove excess numbers
number = Math.round(number);
// turn back into original whole number
number /= decCount;
alert(number.length); // debugging
alert(num[1].length+' > '+spaces); // debugging
alert(number+"\n"+num[1]); // debugging
}
return number;
}
