||
| #define FLT_EVAL_METHOD /* implementation defined */
|
(since C99) | |
Specifies the precision in which all floating-point arithmetic operations are done.
| Value | Explanation |
negative values except -1
|
implementation-defined behavior |
-1
|
the default precision is not known |
0
|
all operations and constants evaluate in the range and precision of the type used. Additionally, float_t and double_t are equivalent to float and double respectively |
1
|
all operations and constants evaluate in the range and precision of double. Additionally, both float_t and double_t are equivalent to double |
2
|
all operations and constants evaluate in the range and precision of long double. Additionally, both float_t and double_t are equivalent to long double |
