[41,42] Perfect functions

[Werner]

In analogy to % and %CH, %T should also leave Y intact.
This comes close:

Code:

>LBL"%T"
 X<>Y
 ST+ Y
 X<>Y
 %CH
 %
 X<> L
 END

but LASTX may suffer from roundoff.
So that leaves

Code:

>LBL"%T"
 ABS
 CLX
 100
 X<>Y
 ST/ Y
 X<>Y
 X<> L
 ST* L
 X<> L
 END

In this case, I'd go for the imperfect, elegant solution though ;-)

Cheers, Werner
