leadCoefficient(NCRingElement) -- Returns the lead monomial of an NCRingElement

Description

Returns the lead coefficient of an NCRingElement (as an element of the base).

i1 : A = QQ{x,y,z,w}

o1 = A

o1 : NCPolynomialRing
i2 : f = x^2+y^2+z^3

      3  2  2
o2 = z +y +x

o2 : A
i3 : coeff = leadCoefficient f

o3 = 1

o3 : QQ
