An Indian Civilizational Perspective

Excel's fuzzy maths!

The entire world uses Microsoft’s Excel to do its maths on computer! Entire Planning and Forecasting systems of even the largest of the world corporations are built on Excel with all the complex algorithms. What if that foundation has a bug such that it cannot do a simple math? Well that is how it is! Excel has a bug and it cannot really do its maths right!

Microsoft Corp.’s Excel 2007 spreadsheet program is going to have to relearn part of its multiplication table.

In a blog post, Microsoft employee David Gainer said that when computer users tried to get Excel 2007 to multiply some pairs of numbers and the result was 65,535, Excel would incorrectly display 100,000 as the answer.

Gainer said Excel makes mistakes multiplying 77.1 by 850, 10.2 by 6,425 and 20.4 by 3,212.5, but the program appears to be able to handle 16,383.75 times 4.

"Further testing showed a similar phenomenon with 65,536 as well," Gainer wrote Tuesday.
