.NET Forum / Languages / C# / April 2008Formating a floating point number
Hello, I have a float point variable defined as: "float floatVar" with the value of "12.3". I would like to format it using floatVar.ToString() in such a way that the output will be 1. right aligned and 2. it will have 4 characters left of the decimal point and 2 right of the decimal point i.e. “ 12.30”. Any suggestion how best to do that? Thanks EitanB > Hello, > [quoted text clipped - 7 lines] > Thanks > EitanB Experiment with something like: String.Format("{0,-7:0.00}", floatVar) A bit unsure if that 7 should be positive or negative, but one is left-aligned, the other is right, and thus padded to be 7 characters. I think you can use :G2 or a similar syntax as well, to use a format more in line with your regional settings, just with two decimals. If the above example doesn't work, dig into the String.Format function and if you follow the links you'll find something about the format characters for floating point values.

Arne A really simple way would be to use something like... floatVar.ToString("0.00").PadLeft(7) SignatureBlackWasp www.blackwasp.co.uk > Hello, > [quoted text clipped - 8 lines] > Thanks > EitanB Signatureloralosangeles > Hello, > [quoted text clipped - 7 lines] > Thanks > EitanB You can check this link for detail: http://msdn2.microsoft.com/en-us/library/0c899ak8(VS.85).aspx floatVar.ToString("0000.00") --> 0012.30 SignatureThanks, Duy Lam Phuong Free MagazinesGet these publications absolutely FREE for up to 12 months.
