@JavaTypedScript Can you please refactor this to use var ulpdiff = require( '@stdlib/number/float32/base/ulp-difference' ); instead as done here?

@anandkaranubc Thank you for your suggestions, it really worked!

t.strictEqual( y, e, 'x: '+x[i]+', y: '+y+', expected: '+e );
} else {
delta = abs( y - e );
tol = 106.0 * EPS * abs( e );

That's a pretty high number. Are you sure this implementation matches the reference implementation you followed?

Yes it was too high and now i have refactored with your suggestion. New to open source, so I missed it.

delta = abs( y - e );

For debugging, since you are following FreeBSD’s C implementation, you can start by comparing your C implementation with the reference one to identify any differences that could cause such a high tolerance value. After that, run this test file to verify your implementation:

NODE_ADDONS_PATTERN="@stdlib/math/base/special/log10f" make install-node-addons
make TESTS_FILTER='@stdlib/math/base/special/log10f/test/test.native.js' test
