Number with decimal

[asdf]

str1:='100';
str2:='6';

If I would like to divide str1 by str2 and the result is 16.67, not 16.666666666666666
What should I do ?

str1:='32.59';
str2:='40.17';
How can I multiply str1 by str2 and the result has 2 decimal points ?

If you need only display result with 2 decimal places:

var f1, f2: LongInt;  //or Single, or Double ....
begin
f1:=strtoint(str1);  //or strtofloat
f2:=strtoint(str2);  //or strtofloat

floattostrF(f1/f2, ffFixed, 3, 2);    //important is the last place (2)

[asdf]

floattostrF(f1/f2, ffFixed, 3, 2); 

What does '3' stand for ?
And are there any more except '3' ?

What does '3' stand for ?

The last two arguments is the same as formatting output via Write(Ln). The 3rd is the minimum number of spaces while the last is the number of decimals.

And are there any more except '3' ?

Sure, you can adjust the spaces to your needs
