string to double skips last decimal if it is zero?

Here is my Problem.

I need to Convert say "5.550" (string) to double as 5.550 that is double with 3 decimal digits. i have tried IFormatProvider while parsing but no use.it keeps skipping last zero(). Please advice.

Thanks, Kumar M A

double doesn't keep insignificant digits - there's no difference between 1.5 and 1.50000 as far as double is concerned.

If you want to preserve insignificant digits, use decimal instead. It may well be more appropriate for you anyway, depending on your exact context. (We have very little context to go on here...)
