A JavaScript function to parse floating point hexadecimals as defined by the .
This module is tested in two ways. The first one is through a small set of test cases that can be found in . The second one is non-deterministic (sometimes called fuzzing):
Generate a random IEEE754 double precision value x.
Compute its representation y in floating point hexadecimal format using the C standard library function printf since C supports this format.
Give both values to JS testcase and see if parseHexFloat(y) === x.
By default one npm test run tests 100 random samples. If you want to do more, you can set the environment variable FUZZ_AMOUNT to whatever number of runs you'd like. Because it uses one child process for each sample, it is really slow though. For more details about the randomized tests see .
