WebBasically you are trying to cast an array of four 8-bit values which can have any alignment they like (byte alignment) to a 32-bit float value which needs 4-byte alignment. And the two just don't mesh. Instead you need to work the other way around - cast a type that has smaller alignment requirements over the type that has larger requirements. WebPrimitive data types - includes byte, short, int, long, float, double, boolean and char; Non-primitive data types - such as String, Arrays and Classes (you will learn more about these in a later chapter) Primitive Data Types.
