Format number to specific string form

[TKassis]

Dear fellow Labview users,

I'm quite familiar with Labview but for some reason I cannot figure out how to do the following:

I need to format a number (any number given) into a string of the form 'mmmmee' where m is a digit and 'ee' the exponential. For example:

0.0128        becomes 1280-5

1654086      becomes 165403

0.0000006   becomes 0600-9

etc.

I would appreciate any advice.

Thank you!

Here's a quick draft. I am sure some of the regex wizards will come up with something simpler. 😄

It sitll needs some work. For example if the value is zero or negative, or if the resulting exponent is more than 2 digits, you also need extra handling. I currently deal with negative exponents that are more than 1 digit (i.e. 2 digits, including the sign).

This is great! Thank you! Works perfectly. I added the additional filtering.
