C Data Types

Table 7-1 shows how the PowerPC Numerics data formats map to the C floating-point variable types. This mapping follows the recommendations in the FPCE technical report.

Table 7-1 Names of data types

PowerPC Numerics format	C type
IEEE single	float
IEEE double	double
Double-double	long double
