The following sections present detailed information on the standard arithmetic and trigonometric operations that are built into GPL. As a convenience during editing, all of these operations are provided as methods to the MathClass. This allows programmers to display a pick list of the Math methods and easily see all of operations that are available.
As is standard in GPL, conversions between different arithmetic types, e.g. Boolean, Integer, Single, Double, are automatically performed as required. So, it is not necessary to have different variations on these methods to deal with the different possible mixes of input parameter data types. Also, these methods generally produce results that are formatted as Double’s. These results will automatically be converted to smaller data types as necessary, e.g. Double -> Integer, and will not generate an error so long as numeric overflow does not occur.
Table 19-65 briefly summarizes the methods that are described in greater detail in the following sections.
