Re: CHICKEN 6 + R7RS

Sorry, yes, I meant `module`. I've been thinking about R6RS so much that for a moment I lost track of what Chicken's conventions are. I would point to rename-on-export. Chicken doesn't support this, and neither does the R7RS-egg. Most of the time, Scheme programmers do fine without it, but when

No, you do. If a Schemer writes (/ 1.0 -0.0) the result must be -inf.0, not +inf.0. But that fact leads to a better way to compile a negative zero into C: (1.0 / (-INFINITY)). No unions needed. On Thu, Jun 27, 2019 at 6:50 PM Evan Hanson wrote: > Hi John, > > On 2019-06-27 18:28, J

Don't forget to cast them to double, however. To get a negative zero you need an initialized global variable: double negative_zero = 1.0 / -INFINITY; and then negative_zero is the Right Thing. On Thu, Jun 27, 2019 at 5:20 PM Evan Hanson wrote: > Putting this here so it doesn't get lost. > >
