Floor function returning EXC_BAD_ACCESS
- by fastrack20
The cod that I am using contains these snippets of code. I am calling ThetaG_JD with the argument 2455343.50000 which is just a sample Julian date. Every time I run the program, I receive a EXC_BAD_ACCESS on the indicated line. When using gdb and printing out the intermediary values and passing them through the floor function, I get no error, but when Frac() is used it always returns an error.
double Frac(double arg)
{
/* Returns fractional part of double argument */
return arg - floor(arg);
}
double ThetaG_JD(double jd)
{
/* Reference: The 1992 Astronomical Almanac, page B6. */
double UT=0, TU=0, GMST=0;
//THIS LINE
UT=Frac(jd+0.5);
// THAT ONE ^^
jd=jd-UT;
TU=(jd-2451545.0)/36525;
GMST=24110.54841+TU*(8640184.812866+TU*(0.093104-TU*6.2E-6));
GMST=Modulus(GMST+secday*omega_E*UT,secday);
return (twopi*GMST/secday);
}
