Previous Comments: ------------------------------------------------------------------------ [2001-01-27 20:55:06] rasmus@php.net Not sure what you are asking for here. round() exists Modulus exists with the modulus operator. ie. echo 3%2; ceil() exists floor() exists Division obviously exists Trunc sort of exists: echo (int)10.57; Frac can be derived as well. But I suppose that is the one you are asking for a native function for? ------------------------------------------------------------------------ [2001-01-27 20:46:50] Frank@kujawski.Org There are a set of four math function that convert real numbers to integers, trunc is missing. Other functions of use are Frac, Mod, Div. Round: return closest integer to argument, if fractional is .5 then return closest even integer. Ceiling: return smallest integer greater than or equal to argument Floor: return largest integer less than or equal to argument Trunc: if argument is positive, return floor of argument, otherwise return ceiling of argument. Frac: return abs(argument - trunc(argument)) Mod: returns remainder of the division of two arguments Div: returns quotiant of the division of two arguments (I ran into this problem when converting a decimal number to an IP number.) ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=8961&edit=1
