# Number Fields The **NUMBERS** tab contains field types for numeric and sequential data. ```{toctree} --- caption: Number Fields hidden: true --- number-input.md controlled-number.md percentage-slider.md auto-incrementing-field.md computed-value-field.md ``` - **[Number Input](number-input.md)** — Accepts numeric data including measurements, counts, calculations, and scientific readings, with support for integers, decimals, and scientific notation. - **[Controlled Number](controlled-number.md)** — Deprecated for new forms; existing Controlled Number fields remain supported. Prefer "Number Input" with minimum and maximum bounds for new templates. - **[Percentage Slider](percentage-slider.md)** — A slider for integer percentages (0–100 by default) with optional step size. - **[Auto Incrementing Field](auto-incrementing-field.md)** — Generates sequential string identifiers such as specimen numbers and catalogue IDs. - **[Computed Value](computed-value-field.md)** — Derives a number from an arithmetic expression over other fields in the same form, updating automatically and shown read-only to data collectors.
