Number representation in trusted blocks
The number format in trusted blocks.
- All length fields are in binary.
- All binary fields (exponents, lengths, and so forth) are stored with the high-order byte first (big-endian format). Thus the least significant bits are to the right and preceded with zero-bits to the width of a field.
- In variable-length binary fields, that have an associated field-length value, leading bytes that would otherwise contain X'00' can be dropped. Thus, these fields can be shortened to contain only the significant bits.
