real.c provides a fixed-size representation of floating-point numbers that allows for various non-IEEE formats supported by GCC, and also allows functions from dfp.c to be used for decimal floating-point formats. MPFR is used in GCC to provide operations that are nontrivial to implement, especially those that are nontrivial to implement in such a fixed-size context. real.c operations wrap around MPFR ones where appropriate, doing whatever's needed in cases where there are non-IEEE semantics or sets of values. -- Joseph S.
