float_t, double_t

Defined in header <math.h> 
typedef /*implementation defined*/ float_t
-		 (since C99) 
typedef /*implementation defined*/ double_t
-		 (since C99)

The types float_t and double_t are floating types at least as wide as float and double, respectively, and such that double_t is at least as wide as float_t. The value of FLT_EVAL_METHOD determines the types of float_t and double_t.

FLT_EVAL_METHOD Explanation
0 float_t and double_t are equivalent to float and double, respectively
1 both float_t and double_t are equivalent to double
2 both float_t and double_t are equivalent to long double
other both float_t and double_t are implementation defined

Example

#include <float.h>
-#include <math.h>
-#include <stdio.h>
- 
-int main(void)
-{
-    printf("%d\n", FLT_EVAL_METHOD);
-    printf("%zu  %zu\n", sizeof(float),sizeof(float_t));
-    printf("%zu  %zu\n", sizeof(double),sizeof(double_t));
-    return 0;
-}

Possible output:

-
0
-4  4
-8  8
