Can someone explain what this is/was?
- spicymaki 3y agoFrom Merlot.org: Keisan Online Calculator site is provided and supported by Casio Computer Co., Ltd. This site contains various Free Online Calculators that enable you to carry out high accuracy calculation using arithmetic operation system with variable number of digits uniquely developed by Casio.
- numpad0 3y agoA huge collection of fill in blank formulae, like "Travel distance at 10 kph for 10 hr equals to 100 km or 62.137 mi", but seemingly everything the users or their employee needed more than once.
- jansan 3y agoFor me the high precision calculator (with up to 130 digits precision) was the most (only?) useful part of the website. It was a life saver if you needed it. Really sad to see it go. https://keisan.casio.com/calculator https://keisan.casio.com/calculator
- jeffwass 3y agoDo you have an example of when 130 digits of calculator precision are needed?
- jansan 3y agoFor root finding algorithms in some edge cases it helped me decide the multiplicity of a root. Also, when calculating constants I wanted to make sure that the result was as precise as possible without any rounding errors introduced in the calculation.

- estomagordo 3y agoCouldn't you simply use arbitrary precision floating arithmetic with i.e. Python?
- tromp 3y agoYes, python with import decimal can be used, as well as Linux bc, but the question was what you need so much precision for.
- qsort 3y agoI've been nerd sniped. What are the "rules" of these problems? Are you allowed to use calculators and programming? Or should the solutions be pencil and paper only Olympiad-style?
