Issue Details

I am looking for the modulo operation in LabVIEW. Where can I find this operation?

Solution

While LabVIEW does not have an explicit modulo operation, there are a variety of ways to perform modulo in LabVIEW.
  • Quotient & Remainder
​The Quotient & Remainder function is most straightforward. The Remainder output is the result of a modulo operation using truncated division. As such, Remainder has the same sign as the dividend and negative numbers are treated differently than in a traditional modulo operation.
  • ​​Formula Express VI and Formula Node
By using a Formula Express VI or Formula Node, you can type the formula for a modulo operation with two inputs and one output. This performs a traditional modulo operation

The image below shows the difference between modulo implemented in Quotient & Remainder and modulo implemented in the Formula Express VI and Formula Node.
