Modulo, D14 Reserved Variables | HP 50g Graphing, 48gII Graphing

MODULO

The variable MODULO contains a real prime number for use with the modular operations. The default value is 13. It is used by ADDTMOD, DIV2MOD, DIVMOD, EXPANDMOD, FACTORMOD, GCDMOD, INVMOD, MODSTO, MULTMOD, POWMOD, RREFMOD, and SUBTMOD.

PERIOD

Contains the period for CAS periodic operations. The default value is 2π.

PRIMIT

Contains a primitive (subexpression) used temporarily for antiderivitive expression during CAS operat ions.

REALASSUME

The variable REALASSUME contains a list of variables which the CAS assumes are real values.

The variable VX contains the name of the default variable to use for CAS commands which operate on a default variable. It is used by DERVX, INTVX, SIGMAVX, and SOLVEVX.
