◄Summary► ◄Example► ◄Up► ◄Contents► ◄Index► ◄Back► ─────Run-Time Library─────────────────────────────────────────────────────── The frexp function breaks down the floating-point value <x> into a mantissa <m> and an exponent <n>. The absolute value of <m> is greater than or equal to 0.5 and less than 1.0, and <x> is equal to <m>*2^n. The integer exponent <n> is stored at the location pointed to by <expptr>. The _frexpl function uses the 80-bit long double form of arguments and return values. In all other respects, it is identical to frexp. Return Value These functions return the mantissa. If <x> is 0, the functions return 0 for both the mantissa and exponent. There is no error return. -♦-
