I have a c-code where I define some variables for pre-processing using the #define command.
However, I think that there are ways to toggle between float and double data types by doing for example:
#define 1.0f // float data type
or
#define 1.0 // double data type
Is there a way I can use it to set a variable of long double data types?
>Solution :
Suffix the float constant with l or L to give it type long double:
1.0L
Do note that float constants only have meaning to C. As far as the preprocessor is concerned, that’s just a string of four characters, no different from any other.
