Hi,

Are the following evaluations in new symbolics expected
by design (or a bug)?

Case A:
-----------
sage:  sin(1.57);  f = sin;  f(1.57)
0:999999682931835
0:999999682931835
-----------

Case B:
-----------
sin(1.57); f(x) = sin(x); f(1.57)
0.999999682931835
sin(1.57000000000000)
---------

For some reasons, sin(1.57) does not get evaluated in case B.

This is in contrast to sage 3.4 where both cases result numerical
evaluation of sin(1.57).


Cheers,
Golam
