float to bytes conversion using c code in labview

[ranazeeshanali]

sir i did the tast of float to bytes conversion using type cast in labview. now i also want that conversion using c code. means i want to know that how much labview can suport c code. farmula node is not suporting my code which is working wel in labwindows. kindly help me about that so that my skil can be improved using labview

Hi ranazee,

you should show us your "C code" so we can tell you why the formula node doesn't support it…

ist kindly tel me that every work that we can do in c that work can be done in farmula node?

Hi ranazee,

all the features supported by the formula node are listed in the LabVIEW help. What else do you need?

[ranazeeshanali]

can the code of float to bytes conversion can run in framula node in university we tried but not succedded

A formula node is not supposed to support a LabWindows program. If you want to call C program, make a dll from it and use the Call Library Node function.

The Formula Node as its name implies is for easy entry of algebraic formulas in text form and uses a C like syntax but is by no means a fully featured C parser/compiler. It only supports a subset of the C syntax for obvious reasons. Why would you need to implement fully fledged C code in a LabVIEW program since LabVIEW supports the same functions and in doing it with LabVIEW nodes you always will have better performance than you can get in the formula node.

If you have real C code you want to call in LabVIEW you don't use the formula node but create a DLL from it and call it through the Call Library Node.
