Number Seperator Formatter

[fowlplay4]

It's a lot easier to make out a million when it's written as 1,000,000 instead of 1000000.

Function:

separate(value, [separator]);

If separator isn't passed it uses a comma.

PHP Code:

function separate(val, sep) {
  // Set chars to separate numbers by
  temp.chars = 3;
  // Negative Number Support
  if (val < 0) {
    val *= -1;
    temp.negative = true;
  } else {
    temp.negative = false;
  }
  // Check if requires separation
  if (val >= (10 ^ temp.chars)) {
    // Decimal Support
    temp.dpos = val.pos(".");
    if (temp.dpos >= 0) {
      temp.newval = val.substring(temp.dpos);
    } else {
      temp.dpos = val.length();
    }
    // Begin Separating Numbers
    for (temp.i = temp.dpos - temp.chars; temp.i > 0; temp.i -= temp.chars) {
      temp.newval = (sep ? sep : ",") @ val.substring(temp.i, temp.chars) @ temp.newval; 
    }
    // Append Final Section of Number
    temp.newval = val.substring(0, temp.chars - abs(temp.i)) @ temp.newval;
    // Make negative if neccesary
    if (temp.negative) temp.newval = "-" @ temp.newval;
    // Return Separated Value
    return temp.newval;
  } else {
    // Make negative if neccesary and return value
    return val * (temp.negative ? -1 : 1);
  }
} 


Usage:

PHP Code:

function onCreated() {
  for (temp.i = 0; temp.i < 10; temp.i++) {
    echo(separate(10 ^ temp.i));
  }
  for (temp.i = 0; temp.i < 6; temp.i++) {
    echo(separate(-(10 ^ temp.i) + 0.15));
  }
} 


Output:

PHP Code:

100
1,000
10,000
100,000
1,000,000
10,000,000

A lot nicer than the one I wrote, thanks for sharing.

Doesn't work for negatives or numbers containing a decimal.

Right, added it in.
