---------------

deg(POLY,VAR)
     :: The degree of a polynomial POLY with respect to variable.

mindeg(POLY,VAR)
     :: The least exponent of the terms with non-zero coefficients in a
     polynomial POLY with respect to the variable VAR.  In this manual,
     this quantity is sometimes referred to the minimum degree of a
     polynomial for short.

RETURN
     non-negative integer

POLY
     polynomial

VAR
     indeterminate

   * The least exponent of the terms with non-zero coefficients in a
     polynomial POLY with respect to the variable VAR.  In this manual,
     this quantity is sometimes referred to the minimum degree of a
     polynomial for short.

   * Variable VAR must be specified.
