This is the correct answer because step="0.01" not only validates the decimal precision but also allows the user to insert decimal values in place of default integer – Farhan Ibn Wahid Commented Jan 11, 2021 at 6:07
I suppose it might mean that the OP is using decimal.Decimal and is unhappy with decimal context's precision which limits precision to n digits as in "n digits of precision in the strict sense" (e.g. '123.456' becomes Decimal('1.2E+2')) and not "n digits in the fractional part" (for Decimal('123.45'))...
DECLARE @Number DECIMAL(5,2) SELECT @Number = 123.65 SELECT FormattedNumber = CAST(CAST(@Number AS DECIMAL(3,0)) AS VARCHAR(4)) Returns '124'. The only thing to consider is whether you want to round up/down, or just strip the zeroes and decimal points without rounding; you'd cast the DECIMAL as an INT in the second case.

My customer needs to insert decimal values all over the place (Prices, Discounts etc) and I'd like to avoid some of the repeating validation. So I immediately tried the MaskedTextBox that would fit my needs (with a Mask like "€ 00000.00"), if it weren't for the focus and the length of the mask.
Decimal provides a high level of accuracy and it's more precise than Float.

To allow numbers with an optional decimal point followed by digits. A digit in the range 1-9 followed by zero or more other digits then optionally followed by a decimal point followed by at least 1 digit: Notes: Update to handle commas: In regular expressions . has a special meaning - match any single character.
It's not clear whether OP actually meant the decimal.Decimal standard library class, or the built-in floating-point type. However, either way, a better version of the question exists. However, either way, a better version of the question exists.
