getFloat64 method

double getFloat64 (int byteOffset, [ Endian endian = Endian.big ])

Returns the floating point number represented by the eight bytes at the specified byteOffset in this object, in IEEE 754 double-precision binary floating-point format (binary64).

Throws RangeError if byteOffset is negative, or byteOffset + 8 is greater than the length of this object.
