represetation of floating point numbers

represetation of floating point numbers

Hi, does anyone know how does ifc represents double floating point numbers, real numbers, complex numbers and double complex numbers? For instance how does the 32 bits assigned in the representation of real numbers? Which bits are used for sign information and which bits are used for mantissa and etc.
If anyone could explain the roles of bits in the representation of these mentioned number types. I would be very glad.

For more complete information about compiler optimizations, see our Optimization Notice.

It's in accordance with the IEEE 754 standard, with byte ordering the same as integer byte ordering. For instance, single precision has the sign and biased exponent in the high order (last) byte, and the unsigned mantissa with high order bit suppressed, in the other 3 bytes. I think some of the better references are squirreled away in the IEEE web site, to which your librarian may have a subscription. You could look up the gnu software floating point packages, if that's your interest.
