The Google calculator is a software calculator available to anyone using the Google search engine by typing commands in the search box. The Google calculator can handle basic arithmetic, namely addition, subtraction, multiplication, division and square root (including those commands containing parentheses); unit conversions; percentages; calculations relating to certain very well-known constants.
The first example provided by Google is
5+2*2. The Google calculator obeys the rules of operator precedence and understands parentheses:
3*(18-2)-1 correctly evaluates to 47. Sometimes the calculator understands the tacit multiplication operator, but it is best to always state it explicitly. The calculator will sometimes insert parenthesis into the expression to show it has understood correctly, e.g., in response to “$125 + 6% of $125” it answers with “(US$ 125) + (6% of (US$ 125)) = 132.5 U.S. dollars.” For sufficiently large numbers (for example, powers of two greater than ) it switches to scientific notation. Like most hardware calculators, the Google calculator also responds to
0^0 with 1.
Commands can also be given in word form, for example, “two times two” or “thrice pi”, which evaluate to “four” and “9.42477796” respectively. Some of the more archaic number names can also be used, such as “gross” (for 144) and “score” (for 20).
