# Square Root A simple arithmetic function block that calculates the square root of a numeric value. Use this block when you need the positive root of a non-negative number inside your scenario. ## 📥 Inputs (sockets) `Number` The numeric value to compute the square root of. Provide a non-negative value for valid results. ## 📤 Outputs (sockets) `Number` The resulting square root value. ## 🕹️ Controls This block has no interactive controls. It computes its output directly from the input socket. ## ⚙️ Running mechanism When the block receives a numeric input, it produces the square root of that value at its output each evaluation cycle. If the input is missing or invalid for square root (for example, a negative number), the block will not produce a meaningful numeric result — include a check before feeding such values. ## ✨ Features * Instant numeric operation suitable for live pipelines. * Minimal UI footprint — designed to be combined with other math and logic blocks. * Works seamlessly in arithmetic chains (e.g., combine with multiply or divide blocks). ## 📝 How to use 1. Provide a numeric value into the `Number` input socket (for example from a `Number Input` block or the output of another math block). 2. Read the result from the `Number` output socket. 3. If you expect negative inputs, validate first (see tips below). ## 💡 Tips and Tricks * Feed values using `Number Input` for manual testing or parameter tuning. * Validate input non-negativity with `Greater` before connecting to avoid invalid values. * If you want to compute the square root of an absolute value, use `Absolute` before this block. * Round results for display using `Round` if you need fewer decimals. * Use `Multiply` or `Divide` before/after to scale values into the desired range. * Visualize numeric trends with `Scope` or log values with `CSV Export` or `Data to JSON` for monitoring. ## 🛠️ Troubleshooting * If the output looks incorrect, ensure the input value is non-negative. * If no value appears, confirm the input socket is connected (for example, from a `Number Input` or another math block). * Use a simple pre-check chain (`Greater` → conditional flow) to prevent invalid inputs from reaching this block. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
