Humm... It tried to tell me that cos(0) does not equal sin(pi/2)... This
is bad:

Depending on the implementation
bit_cast<int64_t>( sin( M_PI / 2 ) )
may be not equal to
bit_cast<int64_t>( cos( 0 ) ).

I was mostly interested in the mathematical truth that cos(0) =
sin(pi/2)... ;^)

Wrt degrees, pi/2 = 90 degrees.

So, I was not really interested in precision issues.
