I DAQ two analogue values from a Helium leak detector: one signal is a step function indicating an exponent (between 1 and 10 Volts, 0.5 V steps) and the other signal indicates the mantissa in the 1-10 V range. I take the mantissa value as it is, and I convert the exponent step function into an integer value. This part is simple. So the leak rate can be constructed in the following way: AI0 * 10^Exponent. I could just use a formula node, but I wonder if there is a neater solution to create a scientific format double? I know there is an inverse function: Edit: Ok, I guess this is the possibly most simple way in LabVIEW, isn't it? -->

I would agree, taking a power of ten to the matissa is what you want. Bob Schor

create double with exponent and mantissa

Solved!

I guess part of the confusion here is that the above function is NOT the inverse function for your problem, because it uses 2^exponent, not 10^exponent.
