DeskCalc has four calculator modes。

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

DeskCalc takes into consideration the different computing ways of conventional devices and thereby can be immediately used by all users without a reorientation

Calculator modes

For the fast keyboard-supported change-over a context menu can be opened by selecting with (<).

Expression Calculator

 

 

Pi 3.1415926535897932384626433832795
%

Calculation of percentage, for example 
10% von 100 = 100*pro(10). < /P > < /P >

exp()

Computes the exponent, example: exp(10)

sin() 

Computes the Sine, example: sin(1.45)

asin()

Computes the Arcsines, example: asin(pi/4)

cos()

Computes the Cosines, example: cos(pi/8)

acos()

Computes the Arccosines, example: acos(pi/4)

tan()

Computes the Tangent, example: 4+tan(pi/8)

atan()

Computes the Arctangent, example: 2*atan(pi/4)

log()

Computes the Logarithms (10)

ln()

Logarithm on the basis of the Euler number of 'e' (approx. 2.71828182845905....) 

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.

 

Examples:

Funktion Input Result

Addition/Subtraction

10+5-3-1 11

Multiplication/Division

10*7+20/5 74

Brackets

10*(5.5+10/5) + 1 76

Power of

10**5 50

Root of

9**(1/2) equal to sqrt(9) 3

Sine Cosine etc

1+sin(pi/4)**2 2

Exponential

1e-1 + 0.1e2 10.1

Random
