Is it possible to use a if statement inside #define?

Question

I\'m trying to make a macro with the following formula: (a^2/(a+b))*b, and I want to make sure that the there will be no dividing by zero.

#define

YES you can have an if statement in a macro. You need to format it correctly. Here is an example:

#define MY_FUNCTION( x )  if( x ) { PRINT("TRUE"); } else { PRINT("FALSE"); }
