An extensible, advanced desk calculator
and mathematical tool written in {Emacs Lisp} by Dave

calculator, but it also provides additional features including
choice of algebraic or {RPN} ({stack}-based) entry,
logarithms, trigonometric and financial functions, {arbitrary
precision}, complex numbers, vectors, matrices, dates, times,
infinities, sets, algebraic simplification, differentiation,
and integration.
