double_t
Floating-point type
Alias of one of the fundamental floating-point types at least as wide as double.
It is the type used by the implementation to evaluate values of type double, as determined by FLT_EVAL_METHOD:
| FLT_EVAL_METHOD | float_t | double_t |
|---|
0 | float | double |
1 | double | double |
2 | long double | long double |
| other | implementation-defined | implementation-defined |
