| | | | | | | | | | | | | conj() instead of using expressions like z * I. The latter is bad for several reasons: 1. It is implemented using arithmetic, which is unnecessary, and can generate floating point exceptions, contrary to the requirements on these functions. 2. gcc implements complex multiplication using a formula that breaks down for infinities, e.g., it gives INFINITY * I == nan + inf I. | ||||

needed for cases where GCC's builtin functions cannot be used and for compilers that don't know about them. Approved by: das (mentor) |
