Fastest way to format an array of numbers

[FightOnSCTrojan]

I am collecting 2D array of DBLs to be later processed by other Vis.

 

The process worked fine when I saved the array to a file (standard %.3f, write to spreadsheet) formatting, then later have a separate VI to open the file and process it.

The same process did not work when I tried to process the 2D array on the fly, without saving/opening to file.

 

After debugging, I found out what was holding me back. Yep you guessed it, the formatting. Without save to spreadsheet, instead of “0.000”, the value is not 2.803E-42 (I need to to be 0.000). What is the most efficient way to format the numbers to “.3f”,  on the fly (without saving to file)?

Best,

BTW...My current solution is to covert array to spreadsheet string...then convert the string back to an array....

.3f is the same as a precision of 3 input to the number to fractional string vi (which can handle arrays automatically)

 To keep only a precision of 3 you can also do it numerically by multiplying by 1000, rounding then dividing by 1000. 

Here is a screenshot of the code using the two different methods. The numeric method should be fastest.
