Force decimal point in formatted string to stay in same position

Question

I am trying to format a double that represents a value from -12.00V to 12.00V.

I am having a hard time formatting it so that the string produces always has the decimal point in the middle.

The String.Format() arguments ("{0:0.00V}") I use produces 4 "types" of numbers

0.00V
00.00V
-0.00V
-00.00V

I would like a way to make all of the "types" appear like so

  0.00V
 00.00V
 -0.00V
-00.00V

So that all of the decimal places always line up with each other no matter the value. Is this possible with .Format()? I know there is the alignment argument but that just aligns the entire string to the left or right and not the string within its own "space".

Answer 1

To right-align, add a width specifier:

"{0,8:0.00V}"

that will give you room for the V, two decimals, a decimal point, two significant digits to the left, a sign, and a leading space (or three significant digits and no leading space).

Answer 2

Use the PadLeft function as follows: [YourStringVariable].PadLeft(6) (MSDN Link)
