C to denote numeric functions?
Let's say I have this function:
int epic(int);
I am aware of these naming conventions, are they correct? Are there other very common ones?
long epicl (long);
long long epicll (long long);
unsigned int epicu (unsigned int);
unsigned long epicul (unsigned long);
unsigned long long epicull (unsigned long long);
double fepic (double);
float fepicf (float);

Sometimes, if the return type is different from the argument type (s), a prefix is used to indicate this. Consider for example the following (from C99):
double round(double x);
float roundf(float x);
long double roundl(long double x);
long int lround(double x);
long int lroundf(float x);
long int lroundl(long double x);
long long int llround(double x);
long long int llroundf(float x);
long long int llroundl(long double x);

Okay, you've almost summed up most of them. Some of you forgot:
long double fepicl(long double); /* thanks @pmg */
double epich(double); /* if epic is a hyperbolic function */
On some embedded systems like ARM:
/* disclaimer, once saw them in an unofficial ARM SDK,
* not sure if these conventions are standard */
u8 epic_8(u8);
u16 epic_16(u16);
