Summary
| Type | Default Size | Default Unit | Typical Usage |
|---|---|---|---|
| integer | 8 | 1 | Bit-level integer packing |
| float | 64 | 1 | IEEE 754 double precision |
| binary | all | 8 | Byte-aligned binary data |
| bitstring | all | 1 | Arbitrary-length bit strings |
Remember: Total bits = Size × Unit, and for binaries, this product must be divisible by 8. It’s not quite as strict as “always know where your towel is,” but it’s a rule you’ll want to internalize nonetheless.
