Is a special representation needed for long and float numbers in the code?
In computer programming with C/C++ we put an f letter after a float typed constant number to distinguish it from double type. In C18 language, should/must we do the same thing?
float fPi = 3.14f; // Do we put this "f" in C18 language?
double dbPi = 3.14;
What about the long type?
int iMyInt = 32767;
long lMyLong = 32768?; // Do we use any marking for long-type?
mcc18 does a few things slightly different from the ANSI standard:
integer literals take on the smallest possible type, unless annotated otherwise. So 100 is a char, 300 is an int, 32768 is a long.
double and float are the same type; both are software-emulated 32-bit IEEE floating points.
