Expression Node
Use the Expression Node to calculate expressions that contain a single variable. The following built-in functions are allowed in formulas: abs, acos, acosh, asin, asinh, atan, atanh, ceil, cos, cosh, cot, csc, exp, expm1, floor, getexp, getman, int, intrz, ln, lnp1, log, log2, max, min, mod, rand, rem, sec, sign, sin, sinc, sinh, sizeOfDim, sqrt, tan, tanh.
Right-click the node and select Build Unit String from the shortcut menu to build and edit a string of units.
 |
input is the value that the Expression Node uses as the variable. |
 |
output returns the value of the calculation. |
Expression Node Details
Expression Nodes are useful when an expression has only one variable but is otherwise complicated. Expression Nodes accept any non-complex numeric data type. Use the correct syntax, operators, and functions when creating Expression Nodes.
 | Note The Expression Node accepts only the period (.) as a decimal separator. The node does not recognize localized decimal separators. |
Example
Refer to the Expression Node VI in the labview\examples\general\functions\Numeric directory for an example of using the Expression Node function.
