p appears to be shorthand for "decimal point".

Oops! 0xAp001f is 20 decimal. 0xap2f would be *40*, not 100.

C:\c\usenet>gcc -o nan.exe nan.c

C:\c\usenet>nan
NAN=1.#INF00
NAN=20.000000

C:\c\usenet>cat nan.c


#define NAN 0xCp125f
#define MAN 0xAp001f

int main(void)
{

double nan = NAN;
double man = MAN;

printf("NAN=%lf \n",nan);
printf("NAN=%lf \n",man);
return 0;
}
