dec2flt.c is a "C" program that converts Interegers to floating point format. The limiting factor for this program is ATOL, it can't deal with floating point format.
Testing this code I have found 2 things of interest. 1. The program will not/never run on a z180 chip. And 2. There is a slight rounding error between this c program and the basic code. The C code is more accurate in my limited test.
flt2dec.bas and dec2flt are microsoft basic programs to convert a decimal value to hex and back to decimal.
Used to creat the constant hex value for PI .. 40490fdb
I am provideing iotest.asm in case you need to modify the i/o addresses or change the way the program works.
