Nor does the ISO standard actually say so, in classical C89/C90.  It
just says "The value is rounded to the appropriate number of digits."
It does not specify by what rounding strategy.  In C99, there's a long
sermon dealing with it, which boils down to the rounding mode being
controlled by the same functions that control the FPU itself.
