ldegree - lowest degree of a polynomial

Calling sequence:
ldegree(poly [ , expr_2 ])
ldegree(expr [ , indets ]  [ , expr_2 ])
indets  ---> [ expr_1 ...]

Parameter:
poly                    --  polynomial
expr, expr_1, expr_2    --  expressions

Summary:

ldegree(p) returns the lowest total degree of the terms of the polynomial p.
ldegree(p,x) returns the lowest degree of the variable x in p.

The first argument of ldegree is allowed to be a polynomial or an expression
and optionally a listof indeterminates.  An expression is converted into a
polynomial in the specified indeterminates (see function poly).  ldegree
returns FAIL if the expression cannot be converted into a polynomial. ldegree
is a kernel function.
