Parameter description
| Interface variable | Declaration | Data type | Description |
|---|---|---|---|
| IN1 | Var_Input | ANY_NUM | Base |
| IN2 | Var_Input | ANY_NUM | Index |
| OUT | Var_Output | ANY_NUM | OUT:=IN1**IN2 |
Example
The EXPT instruction uses variable a as the base and variable b as the exponent to obtain variable c, as shown in the figure below: three INT type variables are defined, and the EXPT instruction is executed by compiling, downloading, and realizing the result of variable c
warning
- In EXPT, the type of IN1 is ANY_REAL, and the type of IN2 is ANY_NUM. The output should be of the same type as IN1
