How to format a (real) number in Delphi ?

I do not remember how to present a real number (says X:real) as a string, with 2 decimal digits
For example, X contains 123.4567 and I want it to be presented as string 123.45 (so also rounded)

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Try this:
FormatFloat('"Number" #.00',X);

FormatFloat('0.00', X) should be enough. FormatFloat('#,##0.00', X) if you want thousands.
FormatFloat will round your number.

You should use the Delphi function:

FloatToStrF(Extended Value, TFloatFormat Format, int Precision, int Digits);

Precision is the maximum number of digits you want preserved. It does not mean that there will always be that number of digits.

Digits is the number of digits you will have after the decimal point.


FloatToStrF(700.12345678,ffNumber,8,2) = 700.12
FloatToStrF(7,ffNumber,8,2) = 7.00
