php: round up and down to nearest cents

by prettyscripts on 2009-09-29 10:22:17

use php functions round() to round up or floor() to round down.

generic code, based on examples to round to nearest nickel (5c), dime (10c) and quarter (25c):

PHP:

	`$x = 100 / $cents_to_round_to;`
	`$round_up = number_format(round($number * $x) / $x, 2);`
	`$round_down = number_format(floor($number * $x)/ $x, 2);`
