ToDoubleArray() public method

Retrieves value converted to array of double values.

If value is array of double values then it retrieved unaltered.

If value is array of bytes then each 8 bytes are converted to double and added to resulting array. If value contains amount of bytes that can't be divided by 8 without remainder, then null is returned.

If value is array of float values then each element of field value gets converted to double and added to resulting array.

If value is of any other type then null is returned.

return	double[]
