Divide Variables
Usage
status = flex_div_vars(u8 boardID, u8 variable1, u8 variable2, u8 returnVector);
Purpose
Divides the value in the first variable by the value in the second variable and returns the result.
Parameters
| Name | Type | Description |
|---|---|---|
| boardID | u8 | assigned by Measurement & Automation Explorer (MAX) |
| variable1 | u8 | dividend |
| variable2 | u8 | divisor |
| returnVector | u8 | destination for the result |
Parameter Discussion
variable1 is the variable holding the first operand. Valid inputs are variables (0x01 through 0x78) and indirect variables (0x81 through 0xF8).
variable2 is the variable holding the second operand. Valid inputs are variables (0x01 through 0x78) and indirect variables (0x81 through 0xF8).
returnVector indicates the destination for the return data generated by this function. Available return vectors include return data to the host (0xFF), to a variable (0x01 through 0x78), to an indirect variable (0x81 through 0xF8), and return no data (0). Refer to Input and Return Vectors for more detailed information.
Using This Function
This function divides the value in the first variable by the value in the second variable and returns the result to the destination specified by the returnVector.
V1 / V2 = Result
where:
V1 is the value at variable1.
V2 is the value at variable2.
Result is stored in the location pointed to by returnVector.
The result can be returned to a new variable or one of the two input variables, returned to the host computer, or thrown away. In all cases the condition codes are set according to the resulting value. This value is compared with 0, and the appropriate condition code is set: GREATER THAN, LESS THAN, or EQUAL to zero.

Note This function does an integer divide and the remainder is lost. |

Note If V2 = 0, this function returns an invalid function data modal error (–70078). |
