Number Separator / Formatter
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:
