  • Sequence length — 1
  • Tensor width — 1
  • Bytes per stored value — B
SOURCE AND LIMITS

Assumptions: The displayed equation is applied to the entered values in the declared units. Any financial rate is interpreted per the period stated in its input label; no jurisdiction-specific fees, taxes, or product terms are inferred. Counts one dense tensor at the stated element width only; gradients, optimizer state, temporary buffers, padding, allocator overhead, and other layers are excluded.

Limitations: Review the equation, input units, assumptions, and method steps before using the result. This tool is not professional advice.

Method version 1.0.0 · Unit registry and result provenance are shown after calculation. This tool is limited to the documented scope.
