Convert numeric into string, but whitout the non significatives zeros in the decimal part ?

[frdlel]

With the "number to fractional string", we can't automaticaly adjust the precision depending of the non significative zeros we can find at the end of the decimal part. For example, I want a precision of 3 decimals. So if my number is "3.1234", I want a string like "3.123", but if the number is "2.1" I want a string like "2.1" and not "2.100".
Does someone have the solution ?

What version of LabVIEW are you using? With 7, you just use the format into string function and use %#.3f as the format string. The # symbol says to remove trailing zeroes.

I use LabView 6.1

After your conversion to a string, try a match pattern function with 0+$ as the expression and use the before sustring output.

It works, except the "dot" if the number is "4.000", it writes "4." instead of "4".

[Dennis_Knutson]

Then do another match pattern to remove the ".".
