This does not work in Chrome 55.0.2883.75. If I create a form element, place the markup above inside, type '1200' into the input and hit tab away from the element, the text displayed is still '1200' and not '1200.00'. –
I have a decimal column in a table defined as decimal(8,3). I would like to include this column in a Select statement, convert it to a Varchar and only display two decimal places. I can't seem to find the right combination of options to do this because everything I try still produces three decimal places.
When I just bind the TextBox or DataGridTextColumn to a decimal, data entry is a problem. <TextBox Text="{Binding MyDecimal, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}"/>. When I try to enter "0,5" in this TextBox I'll get "5" as a result. It is nearly impossible to enter "0,5" at all (apart from entering 1,5 and replacing ...
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
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.
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.
Use Decimal.Parse to convert to decimal number, and then use .ToString("format here") to convert back to a string. Dim aAsDecimal as Decimal = Decimal.Parse(a).ToString("format here") Last resort approach (not recommended): string s = (aAsDecimal <0) ?
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.
The key difference is that you append the current text value... and allow 0-2 decimal values after the decimal (from 1-2) - then you need to escape '.' otherwise it's treated as an 'any character'. Share
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.
