A Clike programming language

Arithmetic operations (addition, subtraction, multiplication
and division) on numbers, polynomials and rational expressions

Operations on vectors and matrices

List processing operations at the minimum

Several Builtin functions (factorization, GCD computation, Groebner basis
computation etc.)

Useful user defined functions(e.g., factorization over algebraic number fields)

A
dbx
like debugger

Plotting of implicit functions

Numerical evaluation of mathematical expressions including elementary
transcendental functions at arbitrary precision. This feature is
in force only if PARI system (see section
pari
).
