Your all-caps final statement is over the top. I don't know which app you mean by "the App that is sold upon which the Google Calculator is based upon". at 8:50 am [ Comment The result from a Google search bar for sin 260 degrees gives the correct result of -0.98480775301. OR, PUT THESE MISTAKES IN DELIBERATELY AS A FORM OF TERRORISM!!! THE PEOPLE WHO WROTE THESE PROGRAMS HAD TO BE COMPLETE IDIOTS. It means that buildings, bridges, and everything we construct could have horrible life threatening mistakes if the engineers used any of these computer calcuators to make their designs.ĭO NOT TRUST THESE APPS OR GOOGLE CALCULATORS. Since these sin, cosine and tangent calculations are all commonly used in vector LOAD analysis in Civil Engineering. The Google calculator is completely wrong, not even close to being right. Example the sin of 260 degrees is stated as: +0.68323970381. The error is in the calculation of Trig problems and vector analysis. An error that can actually be a major threat to everyone, whether you use it or not. GOOGLE CALCULATOR and also the App that is sold upon which the Google Calculator is based upon has a massive error. The calculator might only be able to read a certain number of significant figures. It is possible that the large numbers involved in Google's Math = FAIL was due to overflow errors. I tried Google calculator one day yesterday. UPDATE (Dec 2018): Google's phone calculator app appears to have solved most of the issues mentioned by Shankland's (old now) article.Ħ Comments on “Google calculator - handy, but not always correct” They should put effort into getting this right, with the amount of resources at their disposal you'd think they could. See Google's calculator muffs some math problems Now, what about those mistakes I was talking about? The following article from writer Steven Shankland shows that when the numbers are huge, the calculator could be off a bit (or a lot). For example, an old 8-digit calculator I have here can go up to 69! only (the answer is 1.71122 × 10 98). This is a problem if you want to find the factorial of some large-ish number. Most hand-held calculators are limited when it comes to large numbers. If you have Google selected as the search in Firefox, the answer will appear as a "suggestion" and you don't even need to leave your current page: There are more examples and information here: Calculator.īTW, you may not need to actually go to the site. Counting (in the study of probability) - Example: If you need to know the number of ways 5 objects can be chosen from 14 objects, put: 14 choose 5.Trigonometric functions - Example: sin(3pi/4).What else can it do? Well, lots, actually. The answer will come back at the top of the search results. Just go to Google and type something like the following into the search field: Have you ever played with Google's nifty calculator?
