MesoCalc: a Mesopotamian Calculator

MesoCalc is a Mesopotamian calculator.
People interested in Mesopotamian mathematics can use it to compute with integers in sexagesimal place-value notation. See the note about the sexagesimal place-value notation (SPVN) and the bibliography below.
The present webpage is the program itself. Its latest version can be found on the official MesoCalc page. You are free to download this page, use it offline on your own computer or smartphone, modify the source code, and even redistribute your modifications under the terms of the GNU General Public License (see the license below).
This program was written in 2013 by Baptiste MÉLÈS (Archives Henri Poincaré, Université de Lorraine) with the scientific assistance of Christine PROUST (CNRS, Université Paris-Diderot) in the framework of the SAW Project (Mathematical Sciences in the Ancient World), headed by Karine Chemla (CNRS, Université Paris-Diderot).
If you see bugs or want new features, please contact Baptiste Mélès.

Available operations:

  • Conversions: from decimal to sexagesimal, from sexagesimal to decimal;
  • Number properties: regularity, prime factors;
  • Addition: addition, substraction;
  • Multiplication: multiplication, reciprocal, quotient, rule of three;
  • Powers and roots: square, square root, cube, cube root;
  • Tables: multiplication tables, table of reciprocals, list of regular numbers, list of reciprocal numbers;
  • Measuring units: add lengths, compute brickage and carriage (nalbalum and nazbalum).
