yabin.el

Introduction

yabin.el is Yet another bignum package for Emacs. In fact, this is only a wrapper of calc, but it's a little bit useful than using directly.

Difference of math-*/calcFunc-* functions

• Parameters are automatically normalized. Floating, string number and also calc package's internal form can be used directly.
• A result is automatically formatted to string number.
• Some operation's behavior is changed as same as Emacs native one, such as yabin-div and yabin-reminder.
• Infinite and NaN automatically converted Emacs native representation.
• Only support integer and floating number. Complex numbers are converted into NaN. For vectors, operation isn't defined. Fractions are supported only as input parameter.

Installation

Put elisp file in your load-path, and require.
