"""This test module tests PrimitiveType based conversions of values to/from bytes

Notes:
    Boolean:
        - Stored as 0x00 for False and non-zero byte for True
    Integer:
        - Stored as 4 bytes in little-endian order
        - 84202 is 0...01|01001000|11101010 in binary
    Long:
        - Stored as 8 bytes in little-endian order
        - 200L is 0...0|11001000 in binary
        - 11001000 -> 200 (-56), 00000000 -> 0, ... , 00000000 -> 0
    Double:
        - Stored as 8 bytes in little-endian order
        - floating point numbers are represented as sign * 2ˆexponent * mantissa
        - 6.0 is 1 * 2ˆ4 * 1.5 and encoded as 01000000|00011000|0...0

    Date:
        - Stored as days from 1970-01-01 in a 4-byte little-endian int

        - Stored as UTF-8 bytes (without length)
        - 'A' -> 65, 'B' -> 66, 'C' -> 67
    UUID:
        - Stored as 16-byte big-endian values
        - f79c3e09-677c-4bbd-a479-3f349cb785e7 is encoded as F7 9C 3E 09 67 7C 4B BD A4 79 3F 34 9C B7 85 E7

        - 0xE7 -> 11100111 -> 231 (-25)
    Fixed:
        - Stored directly
        - 'a' -> 97, 'b' -> 98
    Binary:
        - Stored directly
        - 'Z' -> 90
    Decimal:
        - Stored as unscaled values in the form of two's-complement big-endian binary using the minimum number of bytes for the values
        - 345 is 0...1|01011001 in binary
        - 00000001 -> 1, 01011001 -> 89
    Float:
        - Stored as 4 bytes in little-endian order
        - floating point numbers are represented as sign * 2ˆexponent * mantissa
        - -4.5F is -1 * 2ˆ2 * 1.125 and encoded as 11000000|10010000|0...0 in binary
