5.48 Compiler support for floating-point computations and linkage
It is important to understand the difference between floating-point computations and
floating-point linkage. Floating-point computations are performed by hardware coprocessor
instructions or by library functions. Floating-point linkage is concerned with how arguments are
passed between functions that use floating-point variables.
