Decimal floating-point built-in functions

Decimal floating-point (DFP) built-in functions are grouped into the following categories:

When -qarch is set to pwr6 or pwr6e to target POWER6™ processors, -qfloat=nodfpemulate becomes the default. This means that DFP hardware instructions are generated. Lower-performance software emulation code is generated only when:
Note: C++ only In the prototypes given in the following sections, the C keyword _Bool is used by convention to represent a Boolean type.
