I've noticed that if the Formula control, in Eval Multi-Variable Array.vi, contains a formatted number, like 1.6E+3, the vi will give an error. If, on the other hand, that number was not formatted, like 16000, the vi works fine. This is a LV 6.1 version on Eval Multi-Variable Array.vi. Is this a known bug, or am I using the vi incorrectly?
