-* a _float_ is written as 4 bytes. The float is converted into a 32-bit integer using a method equivalent to Java's [floatToIntBits](https://docs.oracle.com/javase/8/docs/api/java/lang/Float.html#floatToIntBits-float-) and then encoded in little-endian format.
-* a _double_ is written as 8 bytes. The double is converted into a 64-bit integer using a method equivalent to Java's [doubleToLongBits](https://docs.oracle.com/javase/8/docs/api/java/lang/Double.html#doubleToLongBits-double-) and then encoded in little-endian format.

 * _bytes_ are encoded as a long followed by that many bytes of data.
 * a _string_ is encoded as a long followed by that many bytes of UTF-8 encoded character data.
 For example, the three-character string "foo" would be encoded as the long value 3 (encoded as hex 06) followed by the UTF-8 encoding of 'f', 'o', and 'o' (the hex bytes 66 6f 6f):
