[Sbcl-help] IEEE floats and rounding?

[Jeronimo P. <j_...@al...>]

Hello,

I was wondering if SBCL has support for setting the rounding mode
for double-floats?

The standard mentions five modes [0]: "to nearest, ties to even",
"to nearest, ties away from zero", "toward 0", "toward +infinity"
and "toward -infinity".

I need to use more than one rounding mode in my programs, so I'd
have to set the mode several times.

So... Does SBCL support something like this?

Thanks,
J.
