Hello,

I'm showing a constant changing value on a TLabel:

a: double;
Label1.Caption := FloatToStr(a);

If the value is 15.4 it looks like this:
15.4

But if the value is 15.0 it looks like this:
15

I want it to be shown with one decimal no matter if the decimal will be 0.
Like this:
15.0

How can I do this the fastest way (for the processor)?


Thanks in advance!

Use the Format() function to perform the conversion.

FormatFloat('##.0', a)

# means if there will be some number it will be displayed else it will be omited.
0 means if there is some number it will be displayed else 0 will be shown.
