It's got nice interface, but not really "scientific" though.

I always do these tests to any calculator who claims itself scientific.

Code:

A. [1] [/] [3][*] [3] (that is 1 divided by 3 times 3)
Windows calculator -> 1
Tavi's calculator -> 1
B. [2] [x^y] [0.5] [x^y] [2], or [2] [Sqr] [X^2] (that is square root of 2 powers 2)
Windows calculator -> 2
Tavi's calculator -> 2.00000000000002
C. [Deg] [90] Sin (that is sinus of 90 degrees)
Windows calculator -> 1
Tavi's calculator -> 1.00000000000002

Hey, why don't you all try those on other calculators (either S/W or H/W) you know, and let us know the results...

Peace always,
