Summary | 0000332: FIXED: Mistake in C++ implementation of ap::complex::operator/=(complex& z) | ||||||
Description |
Wrong code: if( fabs(z.y)<fabs(z.x) ){ e = z.y/z.x; f = z.x+z.y*e; result.x = (z.x+z.y*e)/f; result.y = (z.y-z.x*e)/f; } else { e = z.x/z.y; f = z.y+z.x*e; result.x = (z.y+z.x*e)/f; result.y = (-z.x+z.y*e)/f; } Correct code: if( fabs(z.y)<fabs(z.x) ){ e = z.y/z.x; f = z.x+z.y*e; result.x = (x+y*e)/f; result.y = (y-x*e)/f; } else { e = z.x/z.y; f = z.y+z.x*e; result.x = (y+x*e)/f; result.y = (y*e-x)/f; } |

Additional Information | Have not checked any other operators. Maybe it is neccessary to check them. | ||||||
