Can someone please answer what I hope to be an easy question? I am trying to convert 8 bytes of a bytea into a float8.
In C# this code looks like:
xCoord = System.BitConverter.ToDouble(arrByte, cnt) ;
But in my plpgsql function, the following gives me an error:
xCoord := substring(arrByte from cnt for 8)::float8;
The error that I get is:
ERROR: 42846: cannot cast type bytea to double precision
I have also tried get_byte, but that seems to only be returning the single byte and not all 8bytes for the float. Thanks in advance.
