approx1 off_grid Error

ajflood · pavanky · commit 1078dd0de607 · 2017-01-20T09:44:37.000-08:00
In the singal.py, for arrayfire.approx1, I found that the off_grid format should be float not double.  Therefore I changed it and it now works as expected.

Sorry if this is not proper procedure for fixing bugs, this is my first time reporting bugs on using github.
