Hello Arsen
You could just use the format statement but in your example it would
give the answer 2.6. To get 2.5 you need to use a truncation. This is
easiest done at the integer level, so multiply up, truncate then divide
back down.
Here is an untested thought:
var
i : integer;
a : single;
s : string;
begin
a := 7751.9 / 2991;
a := 10 * a;
i := trunc(a);
a := i / 10;
s := format('%f5.1,[a]); // s := '2.5'
end;
Does it work? If the answer can be negative, check that you get
truncation to the correct side. If not, use the floor function instead
of trunc.
