What about:
sage: z=RIF(-0.001,0.002)
sage: z.str(error_digit
very Pythonic
too.
Related: if I say "style='brackets'", error_digits is ignored. Why
not allow:
sage: x.str(error_digits=2,style="brackets")
[ 3.1408 .. 3.1429 ]
Two error digits might even be the default for brackets. After all,
if a number is correct to so

I do not understand the behaviour below.
sage: x=RIF(3+10/71,3+1/7)
sage: x
3.15?
sage: x.str(style='brackets')
'[3.1408450704225350 .. 3.1428571428571433]'
Both endpoints start with 3.14, both endpoints round to 3.14.
Surely the display should rath
1.+sqrt(-1)
sage: base_ring(z)
Symbolic Ring
sage: base_ring(real(z))
Symbolic Ring
sage: base_ring(imag(z))
Real Field with 53 bits of precision
