- 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.
