I'm quite sure that they're right, that's why I have the while loop that
prints out the ascii values of each character in buffer. The ascii
values of the pi test print out just the same as the other numbers, but
the pi test works with atof(). Which is why this is so wierd. Although
I didn't think about the exponent character, the (-) is accounted for,
and there are no exponents in my numbers.
This is exactly what I have:
text file (this is actually generated by the program, see the
save_parameters() function):
;Cx
0
;Cy
1
;screen center x
1.5
;screen center y
(-)2
;zoom factor
(-)1.5
;max iterations
250
program output:
