FloatToStrF(floatValue, ffFixed, 18, 2)

Specifies the precision. Check the help for details.

You also can use

FloatToStrF(floatValue, ffNumber, 18, 2)

, which does the same thing but with thousands separators; or

Format('Answer is %.2f', [floatValue])

Format() is approximately equivalent to sprintf() in C.

Just to confuse, there is also FloatToStr and FloatToText, but you usually don't want these. -- Doug Burbidge mailto:doug@ultrazone.com

Will FormatFloat do it ?

Hi

Simply use the following
label.caption:=Formatfloat('0.00',yourfloatvariable);

simply relpace '0.00' with '0.000' etc to change number of decimal places you want
