C++ modf function

[Guest]

hi, I was using the following function in a C++ program. I am now "porting"
it to C# and I can not find an equivalent to: modf function. As described
below.

double modf ( double x , double * ipart );
Split floating-point value into fractional and integer parts.
Breaks x in two parts: the integer (stored in location pointed by ipart)
and the fraction (return value).

So does any know of a function that i can use to find the fractional and
integer parts of a floating-point value?
thanks

double orig, ipart, fractional = 0;
orig = 1.234;

fractional = orig - (ipart = Math.Floor(orig));
