TFunctionParser

TFunctionParser is a parser that enables users to implement math capabilities within their applications so that they can analyze and evaluate mathematical functions. Functions are actually user-defined strings such as "cos(x)*t" that can be changed at runtime. Users can develop database applications, mathematical education suites, financial software or calculators.
A broad range (around one hundred) of mathematical operations and functions are included within this parser. Also, it is possible that users can customize constants, variable names and functions according to their needs.
Among the functions and operations bundled in the parser, users can find adding, subtracting, multiplying, dividing, powers, roots, logarithms, trigonometric functions, arc functions, hyperbolic functions, area functions, statistical functions, random numbers, Bessel functions, integral functions, Gamma functions, step functions, periodical functions, absolute values, mathematical constants and number formats.
It can be used within programming or scripting languages that support COM, such as C#, C, C++, PHP, Perl, Delphi, VBScript, VBA, JavaScript, Java or PowerShell.
TFunctionParser makes it possible to implement algebraic syntax capabilities into the host applications, while also providing support for hexadecimal numbers, angles-to-radians conversion, constants, nesting combining and inserting user-defined functions into other ones as well as evaluation of the users code.Limitations in the unregistered version30-day trial
