Hi ! a small question from a guy that didnt use labview for a while ! i need to use the join number function to join two DBL number A and B to form a new number A.B, just like the join numbers function in the example i would like the results after the join number function to be 1.5 however i understand that the function merge bytes/words together and the result is far from what i expect .... any ways to A and B are extracted from modbus READ register command and are unsigned 16 bit seems easy enough but i need a good refreshment on how those bits, bytes and numeric works together.. doh ! thank for everyone involved, Kudos to all labview champions!

Hi yan, as your description still isn't clear in all details I provide two options, see which one fits your needs:

LabVIEW

Solved!

Join. Then typecast to a SGL number. You get 20.93

When the manual tells you "the number is a float" you should typecast to float (i.e. SGL)...
