Float32Array weirdness

Hello all,

In the latest trunk image, #at:put: in Float32Array seems to miss the
fractional part:

| floatArray |
(floatArray := Float32Array new: 4) at: 2 put: 2.3.
floatArray

==> a Float32Array(0.0 2.0 0.0 0.0)

Hi Stef,
it's a VM problem that has been solved already. It works OK with latest VM.

I cannot reproduce. I am on linux, and I get this:

==> a Float32Array(0.0 2.299999952316284 0.0 0.0)

Ah ok, thanks. It would be good to update the VM coming with trunk
images then (they are from March 3rd)

I forgot to mention I'm on Windows, sorry about that.

We chose to not bundle bleeding-edge VMs with Trunk bundles as a safety net. But you are right. Such a fix might justify updating the VM used for Trunk bundles.

Best,
