LC(F:POLY or VECTOR):C

where C is one of INT, RAT, or ZMOD.

Description
This function returns the leading coefficient of F, as determined by the term-ordering of the ring to which F belongs.

Example
/**/  Use R ::= QQ[x,y];
/**/  LC(x +3*x^2 -5*y^2);
3

/**/  LC(Vector(0,5y+6x^2,y^2));  --***OBSOLETE MANUAL: WORK IN PROGRESS***
