🔹 Propagator

Propagator is a tool designed to compute the uncertainty of a mathematical expression. The result is the variance (σ²), and the standard deviation (σ) is the square root of the variance.

Welcome to v2, which is now available! What’s new?

• 🚀 Enhanced computation performance (now fully powered by Python and Pyodide, unlike v1).
• 🐞 Bug fixes and improved readability (better result factoring and syntax error detection).
• 🎨 Refined user interface for a smoother user experience.

The previous version is still available here.

🔹 Syntax Guide

• ✅ Operations: +, -, *, /, ^ or **
• ✅ Functions: exp(x), ln(x) or log(x), log10(x), sqrt(x), sin(x), cos(x), tan(x), asin(x), acos(x), atan(x) (Uppercase like EXP(x) is allowed)
• ✅ Scientific notation: 2.7e10, -1.4e-6
• ✅ Variables & Numbers: 7.91 * var1, -4.3 + var2, ...
• ✅ Constants: Variables without uncertainty should have the prefix cst_, e.g., cst_rho, cst_k
• ✅ Nested Parentheses: No limit! Example: 7 * (var1 * (4 * (...) + var2) + exp(var4))

🔹 Enter your formula to compute the variance

Examples:

a + b
1.2e-6 * exp(2 + c)
rho * d * epsilon
y = cst_a * x1 + cst_b * x2
a**(1/2), a^(1/2), a**0.5, a^0.5, sqrt(A) or SQRT(a)
