Kanden Japanese calculator

Also it displays conventional numbers.

Kanden　ｖｅｒ.2
What's new ?
New calculation logic has introduced into Kanden2.
Kanden2 can treat unlimited length of numbers.
Kanden2 is suitable for accounting calculations.

Conventional calculators can indicate only 8-12 characters on the number display.
One calculator indicates 8 numbers at most. So max number indicated is "99,999,999".
To add 1 to 99,999,999, you push the buttons, "99,999,999","+", "1", "=".
Then the calculator will show "over flow" or "1. E9".

Kanden2 has no limit, so calculation of long length numbers gives accurate answer.
For example, Kanden2 can do the following.
"one decillion" plus "one" is "one decillion and one"
"1,000,000,000,000,000,000,000,000,000,000,000" + "1"
becomes "1,000,000,000,000,000,000,000,000,000,000,001"

Also, the length under decimal point is unlimited.
Kanden2 can treat very small numbers too.
For example, Kanden2 can do the following.
"1" + "0.0000000000000000000000000000000002"
becomes "1.0000000000000000000000000000000002"

When the answer of division will become an infinite decimal,
Kanden2 use the setting value of maximum length under decimal point.
You can change the setting value in the setting menu.
(0-100 :Default value is 20.)
