Float has the following class comment: "My instances represent
IEEE-754 floating-point double-precision numbers."
FloatArray has the following class comment: "FloatArrays store 32bit
IEEE floating point numbers."
I think what you are seeing is the conversion of 64-bit floating point
to 32-bit floating point. Sorry for the initial confusion about your
expected result.
