FOX Calculator is a desktop calculator written in FOX.
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 base-2 logarithm and exponents, and numeric conversion between hexadecimal, octal, binary, and decimal.
It implements correct operator precedences, and features a constant memory which permanently stores its value even if you exit the calculator and restart it later.
Main features:
- + Addition
- - Substraction
- * Multiplication
- / Floating point division
- AND Bit-wise logical and
- OR Bit-wise logical or
- XOR Bit-wise logical exclusive or
- NOT Bit-wise logical not
- SHL Bit-wise shift left

Sin/Cos calculator is a mathematical comand-line calculator.

I was chatting to this guy on IRC who was moaning about his homework. trying to write a program to do this in bash. I said youd be much better off doing it in C, and wrote this. Gave it to him the next day after theyd finished the chapter.

As it does both, theres two executables, it builds main() depending on preprocessor definition... more in the source file.

Compile with:

gcc -lm sin_rule.c -ansi -pedantic -DSINE_RULE -o sin-rule
./sin-rule

PG Calculator is a powerfull scientific skinable calculator. PG Calculator is an excellent replacement for standard Windows calculator.
PG Calculator works in algebraic and RPN mode. It recognizes real and complex numbers and allows simple vectors manipulations.
There are up to 120 recognized units of measure with possibility to make easy conversions between consistent units.
Enhancements:
- fixed to compile with GCC 4.1.1

Subnet Mask Calculator is a simple PHP script that will return the subnet mask and slash-notated mask for a given number of hosts.
Subnet Mask Calculators purpose of this program is to help people calculate subnets for networks based on the number of hosts (computers).
Installation:
Step 1 - copy subnetmaskcalculator.php into a directory accessible from your web server (/var/www/html/ for example).
Step 2 - Visit http://yourhost.domain.tld/subnetmaskcalculator.php
Step 3 - Enjoy
If you have any trouble, support can be obtained by posts to http://www.vle.org/vle
Enhancements:
- This release changes URL GET from HTTP_GET_VARS to _GET.

MCP2510 Bit Timing Calculator project is a bit timing calculator for the MCP2510.

It is a bit timing calculator which is very easy to use.

All you have to do is to choose the baudrate and the oscilator-frequency.

Sure you can edit and change all setting. You will see a graphical bit timing diagram which show you your current options.

At the end you will get a detailed report of your choosen options. See an example here: mcp2510btn

HowTo

On the first step you have to choose your wished baudrate and the oscilator-frequency.

Second you will get a great table with all avaible baudrate for you oscilator-frequency. The are already choosen some baudrates if your baudrate equals with some on the table. Otherwise you have to select them manually, but you will get deviations to you choosen baudrate. You will the the deviation in percent at the right table.

When you are ready you can go forward to step three.
Here you have first to select your wanted Nominal Bit Time Screenshot 2 [Step 3]and then you can edit/change to values for the single segments of a bit timing.

High Visibility Calculator is a high visibility calculator for people with disabilities.

Large buttons with bold text are easy to push for people with motor control or vision problems.
