LeoCalculator is an application for performing calculation of mathematical expressions these could include not only basic operations but also functions and brackets. LeoCalculator also permits to use of predefined variables.

Perfect companion for working with regular expressions. Easily create regular expressions that match exactly what you want. Clearly understand complex regexes written by others. Quickly test any regex on sample strings and files, preventing mistakes on live data. Use the regex with auto-generated code snippets in C#, VB, Java, Delphi, Perl, PHP, Python, JavaScript, etc. Collect libraries of regular expressions for future use. Detailed tutorial.

CalculatorX is an enhanced expression calculator. It can evaluate an expression for one time. You can use Arithmetic, Logic, Bitwise and Relation operations in your expression. And many system constants and built-in functions can also be used in the expression. CalculatorX even supports the custom variables, custom functions and note-line. You can use Binary, Octal, Decimal and HEXadecimal numbers in one expression to evaluate as well.

#Calculation component is a powerful calculation engine for your applications. This ActiveX component integrates expression parsing and evaluation. It is suitable for heavy-duty number crunching. It also allows defining variables and sets of related formulas that implement spreadsheet-like recalculations. Even it can support matrix, array, note-line and custom-functions in your expression.

This calculator allows natural entry of expressions (i.e. 17-(9*8) - 7 + 34.23). Then it goes beyond just giving you a result, the "steps" box, shows you how it solved the expression step by step. Results are given simultaneously in dec/hex/oct/bin. Great for students and home use. It takes the mystery out of solving complex expressions.
