Functions in the ARITHMETIC menu

The ARITHMETIC menu contains a number of sub-menus for specific
applications in number theory (integers, polynomials, etc.), as well as a number
of functions that apply to general arithmetic operations. The ARITHMETIC
menu is triggered through the keystroke combination „Þ (associated with
the 1 key). With system flag 117 set to CHOOSE boxes, „Þ shows
the following menu:
Out of this menu list, options 5 through 9 (DIVIS, FACTORS, LGCD, PROPFRAC,
SIMP2) correspond to common functions that apply to integer numbers or to
polynomials. The remaining options (1. INTEGER, 2. POLYNOMIAL, 3.
MODULO, and 4. PERMUTATION) are actually sub-menus of functions that
apply to specific mathematical objects. This distinction between sub-menus
(options 1 through 4) and plain functions (options 5 through 9) is made clear
when system flag 117 is set to SOFT menus. Activating the ARITHMETIC menu
(„Þ ), under these circumstances, produces:
Following, we present the help facility entries for the functions of options 5
through 9 in the ARITHMETIC menu (IL@HELP):
