Function Mod

general.cpp:288–297

// parameter to within the range of 0 to 360.

real Mod(real d)
{
  if (d >= rDegMax)         // In most cases, value is only slightly
    d -= rDegMax;           // out of range, so can test for it and
  else if (d < 0.0)         // avoid the more complicated arithmetic.
    d += rDegMax;
  if (d >= 0 && d < rDegMax)
    return d;
  return (d - RFloor(d/rDegMax)*rDegMax);
}


// Integer division, like the "/" operator but always rounds result down.
