You'll need to rewrite question again. Neither your subject line nor your message make any sense to me.
The troublesome phrases:
"the out is in fraction"
"output in 17.22"
"value in point form"
"connect it to true case"
"if its a number I will pass to false case"
Find the vi to find fractional number,hope it solves your problem
Is your problem solved? If so please mark the post (Whichever you think is the best solution for your query). This will help others facing same problem and looking for a solution.
I also know it is unwanted, but in the post jeyanthi mentioned i want connect it to true case if its a number i will pass to false case structure..how to do this? . So only i try to mention wire the boolean to the case structure and do required operation. anyway thanks for the comments.
