This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. parseHexFloat parses floating point hexadecimal string with negative binary exponent to IEEE 754 float
  2. parseHexFloat parses floating point hexadecimal string with fractional mantissa and positive binary exponent
  3. parseHexFloat parses hexadecimal integer string without exponent component
  4. parseHexFloat correctly preserves negative sign for hexadecimal floating point values
