Objects for Complex Arithmetic and Arbitrary Arithmetic
by Paul 19 May '11

19 May '11

G'day friends, The most recent sources I have seen for Fractint still uses C. I have migrated ManpWin to C++ so that I am able to use classes to simplify complex arithmetic, especially using arbitrary arithemetic. For example here is the header file for the BigComplex class: // BigComplex.h: interface for the Complex Bignum class. // ////////////////////////////////////////////////////////////////////// #pragma once #include <math.h> #include "BigDouble.h" #define FALSE 0 #define TRUE 1 #define zerotol 1.e-50 class BigComplex { public: BigComplex(void) { } BigComplex(const BigDouble & real, const BigDouble & imaginary) { x = real; y = imaginary; } BigComplex(const BigComplex & Cmplx1)// Copy Constructor { x = Cmplx1.x; y = Cmplx1.y; } BigComplex(const BigDouble & value) { x = value; y = 0; } ~BigComplex(void); BigComplex operator =(const BigComplex &); // Assignment Operator BigComplex operator =(const BigDouble &); // Assignment to a double Operator bool operator==(BigComplex &); BigComplex operator^(BigDouble &); BigComplex operator^(BigComplex &); BigComplex operator++(void); BigComplex operator +(const BigComplex &); // Addition Operator BigComplex operator +(const BigDouble &); // complex add by double Operator BigComplex operator -(const BigComplex &); // Subtraction Operator BigComplex operator -(const BigDouble &); // complex subtract by double Operator BigComplex operator -(void); // unary minus BigComplex operator *(const BigComplex &); // Multiplication Operator BigComplex operator *(const BigDouble &); // complex multiply by double Operator BigComplex operator /(const BigComplex &); // Division Operator BigComplex operator /(const BigDouble &); // complex divide by double Operator BigDouble x, y; }; extern BigComplex CSin(BigComplex &); // sine of a complex number extern BigComplex CCos(BigComplex &); // cosine extern BigComplex CSqr(BigComplex &); // square extern BigComplex CCube(BigComplex &); // cube extern BigDouble BigCSumSqr(BigComplex &); // real squared + imaginary squared extern BigDouble BigCFabs(BigComplex &); // abs extern double CSumSqr(BigComplex &); // real squared + imaginary squared extern double CFabs(BigComplex &); // abs extern BigComplex CPolynomial(BigComplex &, int);// take a complex number to an integer power extern BigComplex CInvert(BigComplex &); // invert extern BigComplex CExp(BigComplex &); // exponent extern BigComplex CLog(BigComplex &); // log I am still developing it and have created 3 classes: Complex, BigDouble and BigComplex. These simplify fractal code immensely. Is this of interest to anyone in the Fractint fraternity?

So, I suspect that Osuch would be wanting a human readable diff, if I work out how to do this, myself. From the way the code operates, I am gleaning that fractint will already store and interpret zero in a scalemap (as the reference frequency; Another Ay). It will even save zero to parameter files. It won't, however, load zeros from a parameter file. Instead, it interprets them as 1/2/3... If I do this, then Bill Jemison also wants it to display "off" for zero. I could probably get away with putting "Zero means off" in the instructions on the scalemapping screen; F7, and I will see how hard it is to print a string on a condition. In other words, I think a zero should be in parameter files, with a meaning that it does not hav as an exponent in equal temperament; frequency = reference / 2 ^ (1/12) ^ key. I will be reading initiation helpmes regarding free compilers. I think that's djgpp. _______ http://ecn.ab.ca/~brewhaha/ BrewJay's Babble Bin
