FDNL-ZE (Zero-Error Arithmetic)

FDNL-ZE (Zero-Error Arithmetic) is our revolutionary technology that definitively eliminates division-by-zero errors and non-physical values in critical calculations, while maintaining minimal overhead of only 0.3-0.8%.

This solution transforms the reliability of intensive computing systems by automatically intercepting division by zero and providing physically coherent values according to application context, ensuring perfect operational continuity.

⚡ Performance & Reliability

Ultra-minimal overhead: only 0.3-0.8% • 100% interception of division by zero • Coherent values adapted to physical context • Configurable modes: IEEE-754, Regularized, Custom • Transparent integration into existing code

🎯 Operating Modes

IEEE-754 Standard Mode

Strictly respects the IEEE-754 standard while intercepting potential errors before they propagate through the system.

Regularized Mode

Provides physically coherent values based on the mathematical and physical context of the application (limits, asymptotes, continuity).

Custom Mode

Allows defining specific behaviors according to business needs and application domain constraints.

🔧 Platforms & Integration

🧮 Matlab/Simulink

Native integration into your existing simulation models

  • Compatible toolboxes: Control System, Signal Processing, Aerospace
