DesktopCalc is an enhanced, easy to use and strong scientific calculator with an expression editor, printing operation, result history list and integrated help. Desktop calculator gives students, teachers, scientists and engineers the power to find values for even the most complex equation set.
DesktopCalc uses Advanced DAL (Dynamic Algebraic Logic) mechanism to perform all its operation with the built-in 38-digit precision math emulator for high precision.
DesktopCalc combines fast "just-one-click" interface with broad set of functions. It was designed as a software that is handy for both elementary and scientific calculator. DesktopCalc features include the following:
* Possibility to enter mathematical formulas as with a keyboard as with built-in button-panels.
* Scientific calculations - unlimited expression length
* Syntax highlight of math expression and proper operator precedence
* Parenthesis compatible
* Scientific notation
* Calculation range:
- maximal positive number: 1.797E+308
- minimal positive number: 2.225E-308
* All functions, mathematical and physical constants can also be used in expression
- 40 trigonometric, logarithmic, hyperbolic and algebraic functions
- 50 built-in most common mathematical and physical constants
* Clipboard smart functionality
- Cut, Copy and Paste operations

Note: Function and constant names are not case-sensitive. For example, Exp is the same as EXP or exp. The variable, which is the letter "x", is also not case-sensitive.
Note: Text after proper mathematical expression will be ignored by the compiler. You can use this feature to comment your equation set.
Note: In particular, you cannot use ^ for exponentiation, you must use the Power function instead.
Note: All the algebraic, trigonometric, hyperbolic and transcendental routines map directly to Intel 80387 FPU floating point machine instructions.
Note: Desktop calculator handles resulting floating-point values between 2.225E-308 (2-1022) and 1.797E+308 (21024).
Note: As operands you can use numeric constants in any form (2, 2.0, 2e5, 2e-3) with decimal delimiter "period" or "comma", depending on your computer system configuration.
Example of formula: sin(tan(cos(43.243)/ln(9.765))/(tan(34.3)*logbaseN(2;3)))*(x - 1.87e-3)
Thus! If your computer system configuration uses "comma" as decimal delimiter/separator, 9.765 in the above example must be 9,765
Example of formula: sin(tan(cos(43,243)/ln(9,765))/(tan(34,3)*logbaseN(2;3)))*(x - 1,87e-3).
