| Function Name |
EXPT (Exponential) |
|---|---|
|
ST Operator |
** |
|
Description |
The output is Input 1 to the power of Input 2. On Function Block Diagrams, the top input is Input 1 and the bottom input is Input 2. |
|
Arguments |
Input 1 {ANY_NUM} Input 2 {ANY_NUM} For more information on the data types for the inputs and outputs, see Data Type Hierarchy. |
|
Returns |
Output {Same data type as Input 1} The Output = Input 1 to the power of Input 2. |
Example:
Function Block Diagram - EXPT:
The output is the top input to the power of the bottom input. So, if the top input is 3 and the bottom input is 2, the output is 32 (3X3=9).
ST Program - EXPT:
The EXPT function outputs Input 1 to the power of Input 2.
- Output := EXPT (Input 1, Input 2);
Where Output, Input 1 and Input 2 are defined as variables earlier in the ST program. In this case, let's assume Input 1 is 10 and Input 2 is 6. The Expt function returns 1000000 as 106=1000000.
