Brief Description:
This extension extends the standard Math category of MIT App Inventor by providing a wide range of advanced and commonly used mathematical functions not available by default. It is designed to simplify complex calculations for your apps by offering easy-to-use blocks for:

  • Factorials
  • Logarithms (natural and base 10)
  • Power and square root calculations
  • Trigonometric functions including sine, cosine, tangent, cotangent, secant, and cosecant
  • Angle conversions between degrees and radians
  • Basic statistical functions such as mean, variance, and standard deviation
  • Utility functions like rounding, absolute value, minimum, and maximum
  • Prime number checks and utilities (is prime, next prime)
  • Fibonacci numbers and the golden ratio (Pi, Phi)
  • Number theory helpers (GCD, LCM, even/odd checks)
  • Random integer generation and more

The extension is built for stability and ease of use, allowing App Inventor users to implement powerful math operations with minimal effort and clean blocks. Compatible with most Android versions supported by MIT App Inventor.

Documentation

  • Designer Properties:
    No specific properties required; this is a non-visible helper component.
  • Blocks and Accepted Values:
    Each block performs a specific mathematical function. Inputs are typically integers or doubles, and outputs match the expected mathematical results (e.g., double for floating-point results, int/long for integer results). See individual block descriptions for details.[quote="Taho_Lajoux, post:1, topic:152706, full:true"]
