Could somebody who knows about numerical evaluation of symbolic
functions please have a look at #17130. The problem is that there is
some coercion going on *after* calling _eval_().
Look at the difference between the following two (the second has false
precision):
sage: bessel_Y._eval_(RealField(200)(1), 1.0)
-0.781212821300289
sage: bessel_Y(RealField(200)(1), 1.0)
-0.78121282130028868451177004317287355661392211914062500000000
