Use the Arithmetic & Comparison Express VIs and functions to perform arithmetic functions and to compare Boolean values, strings, and numeric values.

Express Numeric
Use the Express Numeric functions to create and perform arithmetic and complex mathematical operations on numbers and to convert numbers from one data type to another. Use the VIs and functions on the Elementary & Special Functions palette to perform trigonometric and logarithmic functions.
Express Math
Use the Math functions to create and to perform logarithmic and trigonometric equations and to compute hyperbolic functions and their inverses.
Express Boolean
Use the Express Boolean functions to perform logical operations on Boolean values.
Express Comparison
Use the Express Comparison VI and functions to compare Boolean values, strings, numeric values, arrays, and clusters.
Formula
Uses a calculator interface to create mathematical formulas. You can use this Express VI to perform most math functions that a basic scientific calculator can compute.
Scaling and Mapping
Changes the amplitude of a signal by scaling or mapping the signal.
Time Domain Math
Performs one of several math functions on time domain signals.
