I'd suggest unless you are a VB.NET programmer that you use C# instead, since you will find more samples in C#. If your form is browser, Office 365, you won't be able to use code.https://www.infopathdev.com:443/forums/thread/115726.aspxMon, 06 Mar 2017 15:14:54 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:115726Jose Leandro0https://www.infopathdev.com:443/forums/thread/115726.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=39&PostID=115726How about using Visual Basic in InfoPath for square root functions?https://www.infopathdev.com:443/forums/thread/115724.aspxFri, 03 Mar 2017 20:25:12 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:115724Hilary Stoupa0https://www.infopathdev.com:443/forums/thread/115724.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=39&PostID=115724There isn't any out of the box way to do this. But you may be able to leverage Excel services if this is not a browser Office 365 form & you have Excel services available on your SharePoint server.https://www.infopathdev.com:443/forums/thread/115718.aspxFri, 03 Mar 2017 14:58:15 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:115718Jose Leandro0https://www.infopathdev.com:443/forums/thread/115718.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=39&PostID=115718How can I apply a square root in a formula in InfoPath form?
