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?

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 

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.)
