Leading zeros to the right of the decimal are significant digits if they are between the decimal and number. Think about it mathematically.

0.23 = 23/100

0.023 = 23/1000

0.0230 = 230/10000 or 23/1000

Obviously, trailing zeros are not significant. 0.0230000000 is the same as 0.023

You should use "VSET NSD=3" is you want your result to be 0.023, which is 3 significant digits.
