Where to get it?

Introduction

FOX Calculator can be downloaded from the download page either as a Linux or as Win32 Binary (both statically linked with FOX). The source code for FOX Calculator can be found in the FOX distribution. FOX Calculator is GPL Licensed. The FOX Calculator is a simple desktop calculator geared toward the programmer. It supports not only a full complement scientific functions, but also common operations that programmers need, such as bitwise operations, bitwise shifting, and base2 logarithm and exponents, and numeric conversion between hexadecimal, octal, binary, and decimal. The FOX Calculator implements correct operator precedences, so expressions like 2+3*5 yield the correct result, which is 17, and not 25. Also featured is a constant memory, which permanently stores its value even if you exit the calculator and restart it later.
Configuration

Pressing on the calculator icon brings up the Calculator Preferences dialog. The Calculator Preferences dialog comprises three settings:
In the Calculator settings panel, you can change font used for the display, by pressing the "Set..." button to bring up the standard Font Selection Dialog. You can change the way numbers are printed as well. Checking "Always show exponent" will cause the calculator display always to display the number in exponential notation. Checking "Never show exponent" will cause the calculator to render the number in simple dot notation. The precision can be set by means of the spin button; the default precision is set to 16. Finally, the calculator can be set to beep when errors occur.
In the Color settings panel, you can change the colors of the various button groups. The buttons are grouped by function; the numbers are in one group, and the operators are in another, and so on.
In the About panel, some information is presented about the calculator, like version number and author's contact.
Entering Numbers

You can enter a number by clicking on the digit buttons, or simply hit the right digit on the keyboard. Numbers in exponential notation are entered by entering the mantissa first, then hitting the "EXP" button, and then entering the exponent. Up to 3 digits may be entered for the exponent; entering more than 3 will cause the digits to shift, i.e. the first digit entered will be dropped and replaced by the second, the second digit will be replaced by the third, and the third will be replaced by the new input. Changing the sign of the exponent is accomplished by hittin the "+/" button. At any time, you can hit the Backspace key to delete the last digit entered. Two numbers, pi and e (euler's number) may be entered with a single button:
Operators

The operators in the FOX Calculator are the usual suspects:
In addition, FOX Calculator also includes bitwise operators, such as:
Also nice for programmers is the inclusion of integer operations:
All the operators have certain precedence relations with each other, so that an expression is evaluated correctly.
Trigonometric Functions

The Calculator incorporates the usual trigonometric functions:
Other Functions

Other functions supported by the calculator are the following:
Limits

The calculator works in IEEE 746 double precision mode; for bitwise operations, it uses 32 bit integers. Thus, the numeric limits are as follows:
