Expression Parser
A LabVIEW tool for calculating numerical values
What is Expression Parser?
The LabVIEW tool Expression Parser gives you the ability to calculate and evaluate numerical values from mathematical expressions represented as text strings. This allows you to define and modify mathematical expressions at runtime, rather than being forced to define them statically at edit time.
Expression Parser includes a built-in Expression Tester, so you can be confident that your mathematical expression can be evaluated when you use the tool.
Expression Parser supports more than 260 mathematical functions and constants and delivers calculated results as optional values in any of LabVIEW’s 14 numeric data types.

Efficient math handling in LabVIEW
Evaluating mathematical expressions is an important part of any programming language — and especially in LabVIEW, as LabVIEW is often used in domains where mathematics is fundamental. For example, in simulation, modeling, machine control, and signal processing.

*Expression Parser is only covered by a developer license. One developer license activates Expression Parser in the LabVIEW development environment on one computer, so it can be used by all developers on that computer. Please note that each development environment requires its own Expression Parser license, which includes automated build systems such as CI. The developer license also provides access to support and free updates for the purchased version of Expression Parser.
**There are no runtime costs associated with Expression Parser. If you embed Expression Parser in your applications, you may distribute those applications in as many copies as you wish. This requires no additional licenses.
***Please note that all prices are excluding VAT.
At Sikorsky, we used GPower Expression Parser for a flight telemetry processing project, where we performed around 60,000 evaluations of parsed expressions per second. The flexibility users gained in the compiled runtime environment was impressive.

Dynamic evaluation
Define and customize mathematical expressions as text strings instead of writing them directly in code.
Advanced control
Supports conditions, functions, pulse trains, and user-defined periodic functions.
High performance
Evaluate mathematical expressions millions of times per second — on par with static function blocks.
Flexible variable and data type handling
Supports unlimited variables with optional names, as well as all 14 numeric data types in LabVIEW.
Large function library
Over 260 mathematical functions and constants enable you to work with everything from simple calculations to advanced expressions.
Robust error handling
Automatic overflow detection and clear error messages for syntax and evaluation errors, making expressions easier to debug.
