Description changed by jdemeyer:
Old description:
> The RealNumber constructor does not respect the specified rounding mode
> when constructing from an integer literal:
> {{{
> sage: a = 1.5
> sage: RealNumber(a, rnd='RNDU').parent()
> Real Field with 53 bits of precision and rounding RNDU
> sage: RealNumber(1.5, rnd='RNDU').parent()
> Real Field with 53 bits of precision and rounding RNDU
> sage: RealNumber(2, rnd='RNDU').parent()
> Real Field with 53 bits of precision
> }}}
New description:
The RealNumber constructor does not respect the specified rounding mode
when constructing from a short literal:
{{{
sage: a = 1.5
sage: RealNumber(a, rnd='RNDU').parent()
Real Field with 53 bits of precision and rounding RNDU
sage: RealNumber(1.5, rnd='RNDU').parent()
Real Field with 53 bits of precision and rounding RNDU
sage: RealNumber(2, rnd='RNDU').parent()
Real Field with 53 bits of precision
}}}
