4allCalc is a calculator with scientific and programmer functions, calculating with variables, Regression, easy transfer to/from the clipboard, detailed error messages, and English and German online help.

4allCalc does not try to simulate a real calculator: For example, it does not have an "=" button. The notation of the formulas is like in a programming language. Nevertheless, there is a calculator-like mouse interface.

4allCalc recalculates the result after every keystroke. You have an entry field and a separate result field. If a formula is incomplete or erroneous, 4allCalc will display a detailed error message instead of the result. You can choose between different output formats.

4allCalc also:

• Supports easy transfer of input and output through the clipboard.
• Enables calulating with variables: X in the main entryfield will be replaced by the content of the X entryfield.
• Recalculates variables like X if the result is given
• Supports scientific functions
• Offers programmers functionality: hexadecimal, octal, binary and Ascii input, overflow simulation of integer variables.
• Remembers the last 20 inputs ("history list") and saves formulas.
• New in 4.0: access to the history and saved formulas via dropdown list.
• Supports hypertext online help. Press the help button and the button you want explained. You can simply press F1, too. Or, press help two times to get the help contents.
• Calculates with double precision floating point values, so you have 15 correct digits.
