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.

expressions, and conversations in the target language. LiP is for those who wish to begin speaking right away, because its focus is on real-world phrases and expressions. Each phrase is spoken not only in French, but also in English for reinforcement. It has a unique system of literal translation in which each expression is decomposed into its most logical literal equivalent, conveying the grammar structure used to create the expression. The flashcard

expression should be specified at run-time, not at compile-time. This implies that the expression must be scanned, parsed and evaluated at run-time, which is why you need an expression evaluator. A simple expression evaluator would parse an expression and create a "syntax tree". The expression "a + b * c", for example, would compile into a "Sum" object who`s first operand is parameter "a" and who`s second operand is a "Product" object who`s operands

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.

expressions are using basic concept of the masks but they add even more special characters that can represent definite number of characters, optional phrases etc. You can specify expressions representing complex patterns that are difficult or impossible to find using only masks, such as: e-mail addresses, telephone numbers, IP addresses etc. In the Unix-class systems regular expressions are handled by a program called GREP (Global Regular Expression
