Accuracy of Free42 and DM42

[J-F Garnier]

Actually I'm using most of the time the same version 1.5.5 on my every-day computer, and confirm Dieter's observation.
And also:
SIN(30) is ok,
SIN(60) is ok,
SIN(45-1E-30) is accurate at about 1e-32

Seems related to the special value 45°.

And (in RAD mode), SIN(PI/4) is ok.
