INVMOD
Type:	Function
Description:	Performs modular inversion on an object modulo the current modulus.
Access:	Arithmetic, !ÞMODULO L
Input:	An object.
Output:	The modular inverse of the object.
Flags:	Exact mode must be set (flag –105 clear).
	Numeric mode must not be set (flag –3 clear).

Example: Solve the following for x, modulo the default modulus, 13.

(2x ≡ 1)

Command: INVMOD(2)

Result: -6

IQUOT
Type:	Function
Description:	Returns the integer quotient (or Euclidean quotient) of two integers. That is, given two integers, a
	and b, returns the integer q, such that:
	a = qb + r, and 0 ≤ r < b
Access:	PARITH or Arithmetic, !ÞINTEGER L
Input:	Level 2/Argument 1: The dividend.
	Level 1/Argument 2: The divisor.
Output:	The integer quotient.
