Stdlib: High-Precision Mathematical Functions (Open Source Contribution)

Overview

Contributed to stdlib, a scientific computing library, by implementing high-performance and IEEE-compliant mathematical functions in both C and JavaScript.

Motivation

Accurate numerical computation is critical in scientific and engineering applications.
The goal was to implement functions with high precision, performance, and cross-language compatibility.

Tech Stack

C, JavaScript, Node.js

Work Done

• Implemented:

  • exp10f (base-10 exponential function)
  • csignumf with .assign and .strided variants

• Built complete packages including:

  • Native C implementations
  • JavaScript bindings
  • Benchmark suites
  • Unit tests

• Followed IEEE-754 floating-point standards

Technical Highlights

• Handled floating-point edge cases:

  • Overflow / underflow
  • Precision loss
  • Special values (NaN, ±Inf)

• Ensured bit-level correctness

• Achieved high test coverage and passed strict validation suites
