◄Summary► ◄Example► ◄Up► ◄Contents► ◄Index► ◄Back► ──────────────────────────────────────────────────────────────────────────── The modf function breaks down the floating-point value <x> into fractional and integer parts, each of which has the same sign as <x>. The signed fractional portion of <x> is returned. The integer portion is stored as a floating-point value at <intptr>. The modfl function uses an 80-bit long double form of arguments and return values. In all other respects, it is identical to the regular function. Return Value The modf and modfl functions return the signed fractional portion of <x>. There is no error return. -♦-
