Utility Routines
The following is information on the floating-point, complex number, and other math
routines.
Floating-Point Math
• All of the floating-point math routine arguments are input in OP1 or OP1/OP2, and
output in OP1, unless noted below.
• Errors can be generated by the math routines. See the Error Handlers section.
• All of the inputs to these routines are floating-point numbers.
• See the System Routine Documentation, entry points UnOPExec and BinOPExec
to access this functionality with arguments other than floating-point numbers.
