The following sections present detailed information on the standard functions that are supported by GPL. These functions are not grouped into a specific Class and are provided in this manner to be compatible with other Basic Language systems. 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 functions to deal with the different possible mixes of input parameter data types. Also, these functions 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. summarizes the system functions that are described in greater detail in the following sections.
