Math Mode Help Information

These menu items control which data
type is used when generating
pictures.  The data type affects two
aspects two picture generation:
speed of calculation and accuracy of
calculation.

Unless you have a 68020/68881 based
Amiga, you generally have to trade
speed for accuracy.  You have three
choices for Math Modes:

  Int68000 - fastest least accurate
  FFP - middle at speed and accuracy
  IEEE - slowest and most accurate

You can change a project's math mode
at any time, but the change will not
have affect until the next time you
generate the project.

Typically you would start out using
Int68000.  You would zoom in as far
as you can go, until the picture
starts to look blocky or "noisy".
At this point, you will have to
switch to FFP mode.  You will be
able to zoom in only a few more
times before you will have to switch
to IEEE.  Once you've gotten to IEEE
mode, any picture will be VERY slow
to generate.

For those of you rich enough to have
a 68020/68881 based Amiga, you have
two more Math Modes to choose from:

  Int68020 - fastest least accurate
  68881 - slower than Int68020 but
          as accurate as IEEE

Int68020 has the same accuracy as
Int68000 but uses more efficient
68020 machine instructions and is
therefore faster.

68881 Math Mode uses the 68881 math
coprocessor to calculate pictures.
This is not as fast as the 68020,
but is much more accurate.
