You probably mean IEEE 754. The C standard doesn't mandate the use of IEEE 754 floating point arithmetic. The implementation may choose to implement it: in this case, it should define __STDC_IEC_559__ macro to allow applications that care to detect this fact (and, e.g., switch from emulation library to native instructions). C99 appendix F defines how C language constructs correspond to IEEE 754 types and operations (for those implementations that claim to support IEEE 754). Nowadays, it would be difficult to find a piece of hardware, or a C implementation, that supports floating point arithmetic but doesn't follow IEEE 754.
