Hey Bubble devs! 👋
I'm excited to introduce the Dual List Math Engine — a powerful no-code plugin that brings real list-to-list math operations to your Bubble app!

Whether you're building financial calculators, data analysis tools, dashboards, or any app that compares or computes across two lists of numbers — this plugin gives you all the core operations you need.

Key Features:

Perform math operations on two comma-separated lists 🧮

Supports: add, subtract, multiply, divide, percent_change, absolute_difference, cumulative_sum, and product ➕➖✖️➗

Handle uneven lists with optional padding (start or end) 🔧

Round results to your preferred decimal precision 📐

Returns output as:

output_list (comma-separated result) 📋
result_sum (total of values) 🔢
result_dot_product (for vector-style math) 📈

Perfect Use Cases:

💰 Financial calculators and budget trackers
📈 Performance comparison dashboards
📊 Statistical analysis tools
🛒 eCommerce analytics and pricing
📉 Time-series data analysis
🎯 A/B testing result comparisons
💹 Investment portfolio tracking

The Dual List Math Engine intelligently handles lists of differing lengths with optional zero-padding at the start or end, ensuring consistent behavior regardless of input format. The plugin will also replace any empty numerical values as zeros (i.e. 1,2,3, , ,6, 7 will be converted automatically to 1,2,3,0,0,6,7). It also provides optional rounding for output values, allowing developers to control numerical precision directly.

Each operation is processed in parallel across both lists, and results are returned as: A comma-separated output_list, the result_sum of all items, and the result_dot_product (where applicable).

Whether you're building financial calculators, performance trackers, or statistical dashboards, the List Math Engine provides the flexibility, accuracy, and speed you need—without writing a single line of code. Best of all, it's designed with no extra fluff—just clean, efficient logic you can drop into your app immediately.

From eCommerce analytics to time-series analysis, the List Math Engine supercharges your list-based workflows with precision and power 💪.
