6.13.2 Type: dec32
The dec32 type is decimal value with a variable number of digits following the decimal point. It is encoded
as an 8-bit unsigned integral value representing the number of decimal places. This is followed by the signed
integral value encoded using a 32-bit two's complement representation in network byte order.
The former value is referred to as the exponent of the divisor. The latter value is the mantissa. The decimal
value is given by: mantissa / 10^exponent.
