I'm hoping this is the right place for posting my question. This is the error I'm getting in my code...

The error message seems really clear to me. The query variable is a float array -- and you tried to assign an double array to it.

Correct. You should change the assignment to new float[]. That still would not compile because of the 0.0's - those are doubles. If you change those to 0.0f they become floats and the array can hold them.

Agree. And don't use pale green text; it is hard to read. And don't use such long lines; they are hard to read.

Please check Line 57. You may use an index, whose value is bigger than max index of the array.

For example:
