Free version for Windows desktop computers.

DeskCalc has four calculator modes.

• Adding machine ( Commercial Desktop calculator )
• Windows  Calc
• Expression Calculator

DeskCalc takes into consideration the different computing ways of conventional devices and thereby can be immediately used by all users without a reorientation For the fast keyboard-supported change-over a context menu can be opened by selecting with (<).

Fac() Factorizing up to max. 1547, example: fac(10) =  362880 < /P > < /P > Rnd() Random number, example: rnd(100) Deg() Radian change of degree, example: deg(cos(phi/4)) =  40.5142 < /P > < /P > Rad() Degree change of radian, example: rad(180) = 3.1415 < /P > < /P > Sqrt() Square root of, example: sqrt(9) = 3< /P >< /P > x^y X to the power of y, example: 2**4 = 16< /P >< /P >

### Expressions in parentheses ()

You should use each operation in brackets.  Example:  the expression "(10+5)/5" meant that the expression in the brackets is first computed and then the part outside of the braces.  The result of (10 + 5)/5 is 3, without the braces it would be 10 + 5/5 and would thus result in 11.
