Try FloatToStrF. Example below.
Even though Extended is supposed to give 19 or 20 digits of precision, this
function gives you a maximum precision of only 18 digits.
Note also the following extract from the Delphi Help: (Remember that the
maximum precision is 18). "If the number of digits to the left of the
decimal point is greater than the specified precision, the resulting value
will use scientific format."
Var X : Extended; S : String;
X:= -123456789012345678; // 18 digits to left of decimal point - works.
S:=FloatToStrF(X,ffFixed,18,2);
ShowMessage(S);

Subject: Formatting large numbers
Hi,
I need to be able to display very large numbers (precision > 16) in text
strings. After some swearing and shouting, I find that I am able to
manipulate the numbers using the Delhpi Extended data type (Delphi 5
Enterprise).
But I cannot get them to display. Using the formatting routines simply
produces scientific notation - and I need to be able to see the actual
number as a string.
Any ideas?
Regards
Tim
