This function returns a string if more than 1 value was defined.
1.- It adds all the numbers to a list
1.1 Red for negatves, Green otherwise
2.- It concatenates all elements of said lists, wth some extras to make sense.

This function return a string for the case that only 1 value was defined.
1.  If a stack value was defined:
1.1 Is stack equal to 1
1.2 Any other case.
2.  If a stack was not defined, then check the multiplier
2.1 If the multiplier is equal or above one
2.2 If the multiplier is below 1.

Finally, some final code to decide what color to use.
1. Green for positive.
2. None for 0.
3. Red for negatives.
The retuned value is rounded half-down. (Meaning 0.5 -> 0 )
	string.format("%.2f", number))
To combat that, I add 0.001 to the number calculated. It should be enough.
