D.2.2.3 absValue
................
Procedure from library general.lib (see general_lib).

Usage:
absValue(c); c int, number or poly

Return:
absValue(c); the absolute value of c

Note:
absValue(c)=c if c>=0; absValue=-c if c<=0.

 So the function can be applied to any type, for which comparison

 operators are defined.

Example:
LIB "general.lib";
ring r1 = 0,x,dp;
absValue(-2002);
==> 2002
poly f=-4;
absValue(f);
==> 4
