Question on Inverse and Hyperbolic Trigonometric functions

[Paolo]

but now most users don't understand why the condition "if 1.3+1.4 = 2.7"  reports false..

I understand your point ! But consider that not all people have the right understanding about floating point representation and involved math.

I have just a note about the debug-window, consider the code as below

Code: Pascal  [Select][+][-]

1. var
2.   f1, f2 : double;
3. ..
4.   f1:=some calculation
5.   f2:=some calculation
6. ..
7.  

it may happen that the two values are such f1 <> f2 but debug-window still shows the same decimal numbers, let me say something like

f1=3.123456789
f2=3.123456789

you showed me that writestr at least shall report different values on the output string (not the fully expanded decimal I am looking for), why not having at least such representation (the same given by writestr) in the debug windows ? this allow easily (without looking at binary repreentation) see that they are different.

thanks again.

Finally submitted a patch.
Thanks to all who helped.
