- Documentation for the AmigaREXX math library, version 1.0.
- ==========================================================
-
- In version 1 of the AmigaREXX math library the following functions
- have been implemented. In column 1 you will find the function, in column 2
- the calling sequence, and in column 3 some aliases. Column 4 has the allowed
- ranges of the arguments that will not cause an error.
- The regular library is called rexxmathlib.library: it should work on
- all Amigas. However, if you own a StarBoard II memory expansion with a
- Multi-Function Module plus 68881 math coprocessor, you can speed up your
- REXX math by using the library rexxmathsbii.library instead. You will then
- also need the MicroBotics supplied IEEE libraries.
