Extract Values to Points gives me null values

I am working with some .flt files from Whitebox. When I try to extract values to points, it spits out a layer that says "null" for all of my raster values. The layers definitely overlap, and I think my problem is that my .flt file doesn't have attributes. Here are things that I hhave tried:

1) convert my .flt file to a raster, and then give it some attributes. This breaks down at the "Build Raster Attribute Table" because if I follow directions completely and turn it into a 32 bit signed integer there are only two entries in my new attribute table; and if I don't follow those directions and choose the 32 bit float option, it tells me that only "single band integers" are valid.

2) I have also tried straight up converting the float file to a raster in ArcGIS, which tells me it can't because I don't have an attribute table.

Suggestions?
