Complex numbers in compilers - upcoming GNU Tools Cauldron.
This is going to be an interesting discussion. In the upcoming GNU Tools Cauldron meeting the representation of complex numbers in GCC will be discussed from the following "starting point": "Complex numbers are used to describe many physical phenomenons and are of prime importance in data signal processing. Nevertheless, despite being part of the C and C++ standards since C99, they are still not completely first class citizens in mainstream compilers." *This* is from the Fortran 66 Standard (http://moene.org/~toon/f66.pdf - a photocopy of the 1966 Standard): - - - - - Chapter 4. Data Types: ... 4.2.4 Complex Type. A complex datum is processor approximation to the value of a complex number. ... - - - - - I can recall people complaining about the way complex arithmetic was handled by compilers since the late 70s. This is even obvious in weather forecasting software I have to deal with *today* (all written in Fortran). Some models use complex variables to encode the "spectral" (wave-decomposed) computations in parts where that is useful - others just "degrade" those algorithms to explicitly use reals.

hey
This is basically if it has any interest..or else ignore... This inverts the digits. So 321 should be 123..not tested We only invert the ten bases, but it can be ok for others. A) 1*10^4 + 2*10^3 + 3*10^2 + 4*10^1 + 5 * 10^0 B) 10^4 + 10^2 + 10^0 + 10^-2 + 10^-4 Divide A) by B)
