CDouble

(C) double

A standard data type (and thus a keyword) that can hold a single broken number.

double myDouble = 12.34;

Advanced

The double is on some/most environments a 64 bit number. The 0th bit contains the sign of the number. In some environments, this might cause the value 0.0 be unequal to -0.0. The == might yield a true, but in memory this will not be the case.

include <assert.h>


int main()
{
  double zero = 0.0;
  double minusZero = -0.0;
  assert(zero==minusZero)
  return 0;
}
