Simple Open-Collector Comparator with Pull-up Resistor Hysteresis Level (Inverting Schmitt Trigger) Calculator

Most of the calculators on the internet are designed for push-pull output comparator, while they are handy, I do find myself wanting to use an open-collector or open-drain comparator instead.

As described by the title, this is a simple javascript-based calculator to calculate VH and VL.
No styling applied, so, it will look a bit ugly. 😆

There is no input-sanitation, so, make sure to only put plain numbers.
Let me know if you spot any careless mistake in the maths. 😁
