NAME¶

float_t, double_t - most efficient floating types

LIBRARY¶

Math library (libm)

SYNOPSIS¶

#include <math.h>

typedef /* ... */ float_t;
typedef /* ... */ double_t;

DESCRIPTION¶

The implementation's most efficient floating types at least as wide as float and double respectively. Their type depends on the value of the macro FLT_EVAL_METHOD (defined in <float.h>):

For other values of FLT_EVAL_METHOD, the types of float_t and double_t are implementation-defined.

STANDARDS¶

C99 and later; POSIX.1-2001 and later.
