Numerical calculator

This numerical calculator requires that you type your formulas. But it
recognizes much more functions than calculators with buttons, and it knows
how to compute real or complex numbers, as well as numbers modulo an integer
(positive characteristics).

You will also have a modifiable history as well as the possibility of using
results of earlier computations in the following formulas, allowing you to
make various manipulations.
See help for instructions.
