Oddities of Google calculator

5th September 2008

When performing simple arithmetic operations with large numbers Google calculator often makes mistakes. This occurs not always, but it is possible to pick up such numbers, with which the calculator is wrong.
For example, 2999999999999999 minus 2999999999999998 is one, but Google calculator shows the value 0.
Also, for example, when calculating 1999999999999999 minus 1999999999999995, it shows the wrong value 0, but the result of 1999999999999999 minus 1999999999999993 is correct: 6. Also at the request: 400000000000002 minus 400000000000001 you can get invalid value 0, but at the request: 400000000000002 minus 400000000000000 the calculator gives the correct value of 2.
Perhaps the most blatant mistake of the calculator is the wrong result in making operations with the number google (this - number is equal to 0 in the degree of 100, or one with a hundred zeros), which is the base of the search engineâ€™s name. Thus, at the attempt to do the following calculation â€œgoogle +1 minus googleâ€, the calculator gives 0 instead of 1.
