in ref: arrayref: index out of range for Float arrays containing zeros

[stefan-k]

Typing [0.0] leads to
in ref: arrayref: index out of range
Works for Ints and non-zero values. I'm using the last commit and I didn't experience this problem yesterday.

Sorry for posting this twice (actually thrice), I thought it didn't work the first time because I couldn't see the issue myself.
