rounding to nearest even number

[fnbcprog]

I am trying to round to the nearest even number?

101.25 -> 102
101.00 -> 102
100.99 -> 100

Any thoughts or ideas?

Use [man]floor[/man] and then see if the number returned are even or odd. You can do that by using $check = $number % 2. Depending on the value of $check you can either leave the number as it is or add 1 to it.

round($foo/2)*2 might work.
