Google calculator

Am descoperit si eu acum vreo luna si tot intrebam lumea daca stie de ea si tot aflam ca defapt nimeni nu stie, asa ca m-am gandit sa scriu un post despre el, ca sa afle lumea. Si ca sa nu va mai tin in suspans, vorbesc de calcuatorul integrat in Searchbox-ul de la Google, numit Google Calculator.
Cautam intr-o zi o trupa, si am tastat pe Google “3+2” la care el in mod foarte ciudat mi-a dat “3+2 = 5”.

Mai jos era un link, “More about Google Calculator”. Si uite asa am descoperit minunatele facilitati de calcul ale Google-ului.

Sa vedem cateva exemple. Textul scris cu “italics” a fost introdus in casuta de cautare a Google-ului, iar randul sub ele este raspunsul dat de Google Search.

Aritmetica simpla

"5+2"
  5 + 2 = 7

"5+3*3"
  5 + (3 * 3) = 14

"(5+3*3)^6"
  (5 + (3 * 3))^6 = 7 529 536

"(5+3*3)e^-6"
  (5 + (3 * 3)) * (e^(-6)) = 0.0347025305

Operatii hexa si binar

"0x7f + 0b10010101"
  0x7f + 0b10010101 = 0x114

Operatii trigonometrice

"sin(3.14)"
  sin(3.14) = 0.00159265292

"sin(pi)"
  sin(pi) = 0

"tan(pi/4)"
  tan(pi / 4) = 1

"(sin(50))^2+(cos(50))^2"
  (sin(50)^2) + (cos(50)^2) = 1

"sin(pi^2/4)+arctan(pi/2)+tanh(pi/3)"
  sin((pi^2) / 4) + arctan(pi / 2) + tanh(pi / 3) = 2.40886521

Operatii cu numere complexe

"sqrt(-4)"
  sqrt(-4) = 2 i

"2i+(3-3i)"
  (2 * i) + (3 - (3 * i)) = 3 - i

"(3-2i)*(10+3i)*(2-5i)/(4-i)"
  ((3 - (2 * i)) * (10 + (3 * i)) * (2 - (5 * i))) / (4 - i) = 15.8823529 - 46.5294118 i

Conversii de uniati de masura

"100 km in miles"
  100 kilometers = 62.1371192 miles

"95 Fahrenheit in Celsius"
  95 degrees Fahrenheit = 35 degrees Celsius

"60 mph in kph"
  60 mph = 96.56064 kph

"30 mils in millimeter"
  30 mils = 0.762 millimeter

"40 mpg in liters per 100 kilometer"
  40 mpg = 5.88036458 liters per (100 kilometer)

Convertor valutar

"100 Euro in RON"
  100 Euros = 353.917653 Romanian leu

"300 USD in GBP"
  300 U.S. dollars = 155.674329 British pounds

Astea sunt numai cateva exemple din capacitatile inedite a Google Calculator. Mai multe informatii si exemple gasiti pe Google Calculator Help.
