In the calculator’s "SETUP" one can specify its output format. One can choose between "MathO" and "LineO". When set to the former, the result of "SIN(π/4" (yes you may omit the closing bracket!) will be √2/2. When using the latter format the result will of course be "0.7071067812". The calculator should be set to radians of course.
A very capable calculator. Does integration, differentiation, solves equations, does BASE-n calculations, knows complex numbers, matrix- and vector math, and has a library of mathematical constants and unit conversions. A table is required for the mathematical constants and the unit conversions because they have to be addressed by index number. Fortunately this table is printed on the inside of the calculator’s protective case.
It can almost be classified as programmable, for in "CALC" mode one can enter a formula with variables that can be replayed asking for the variable’s values.
All in all, working on this calculator feels very natural. The team that has designed it knows what the user would expect. For instance, when one has a number displayed and one presses the √▖ key = key, the calculator knows one wants to calculate "√(Ans".
Earlier calculators had S-V.P.A.M. (Super Visually Perfect Algebraic Method). This calculator extends that to NATURAL-V.P.A.M.
Not suitable for people (such as me) with a degree of OCD because all the bigger keys are tilted in one direction or another, the holes for the keys is just a little bit to big.
