Pretty easygoing kata to figure out and to solve, nice.

That calculator is wrong, left Riemann sum doesn't include `f(b)`. Not an issue.

JavaScript Solution:

I think in second solution test for cubic polynomial answer is wrong. I cheked my solution with Riemann Calculator Online (https://calculator-online.net/riemann-sum-calculator/) and answer is -4.291875000000000 (how i expected) against -4.441875 of author's test.

The translator did `a - b` instead of `b - a`. This is probably not a mistake worthy of removing the translation.

Fixed.

The python solution setup is still f'cked up

• ###### dfhwzecommented on "riemann sums I (left side rule)" kata

This has still not been fixed. I suggest to remove the Elixir version altogether.

Forked JavaScript translation

• use chai for assertions
• update to Node 14
• remove rounding requirement, use assert.approximately
• print inputs in random tests assertion messages
• ###### Madjoszresolved an issue on "riemann sums I (left side rule)" kata

Fixed. Tests now use `assert_approx_equals()`.

• ###### Madjoszresolved an issue on "riemann sums I (left side rule)" kata

Fixed. Tests now use `assert_approx_equals()`.

Thanks.

Forked Python translation

• replace rounding by `assert_approx_equals()`
• rename `sum` variable in initial solution template
