| Function Name |
EXP |
|---|---|
| Description |
Converts a REAL or LREAL input into a natural exponential value that is the output. The exponential value is also a REAL or LREAL. |
| Arguments |
Input 1 {REAL or LREAL}. For more information on the data types for the inputs and outputs, see Data Type Hierarchy. |
| Returns |
Output {REAL or LREAL} |
Example:
Function Block Diagram - EXP:
In this example, the input of 5 is provided by the CurrentValue property of a point. The EXP function converts the value into an exponential value of 148.413159102577 and this is used as the output.
ST Program - EXP:
The syntax for an EXP function in an ST Program is:
Output := EXP (Input 1);
Where Output and Input 1 are defined as variables earlier in the ST program. The Input 1 variable represents a REAL or LREAL type of value (the output is the same type of value as Input 1).
