![]() The calculation would go on forever, so we have to stop somewhere.Ĭontact us with any suggestions for improvements or enhancements to this full precision calculator. The same thing happens with functions like square root, sine, cosine, etc. Most calculations are done to full precision.īut some decimals go on forever (such as 1/3 = 0.33333.), so we stop after 200 decimals. To estimate how long it should take on your device.Īlso if you want to calculate high powers, for example, 2^1000, it may be quicker to calculate 2^100, then take that result and raise that For example if 200! is taking a long time, then try 100!, then 120! etc In some cases it may be better to approach things more gently. It is up to you whether to continue to run the script or not. I will try to get back to you as soon as possible.2*pi = 6.283185307179586476925286766559.ġ/7 = 0.142857142857142857142857142857142857.Notes: Some of the functions (such as x!, or x^y) may need a lot of calculation, so after some seconds of calculation yourīrowser may complain that a script is running too long.

Ln is called the natural logarithm of a number. It is more often seen as the Greek letter π, but that may not show up in some older browsers. (You can also calculate the square root with x^y, using y = 0.5.) pi The square root of a number is the value multiplied by itself that equals the original number. It is often seen as the symbol √, but that may not show up in some older browsers. Sqrt means the square root of the number. That is 3*3*3*3 or 3 times itself 4 times. For example, if y = 3, you would have x cubed or x 3. You should get 30 (degrees) for an answer. Enter 0.5, click inv and then click sin.Those values are also called the arcsine, arccosine and arctangent. This is called the inverse ( inv) operation. If you know the sine, cosine or tangent, you can find the angle in degrees for that function. There is also the capability of going backwards. If you would want to find the sine of an angle of 30 degrees, you would enter 30 and then the sin button.You need JavaScript activated to use this Flash animation.ġ/x is simply 1 divided by whatever x is.įunctions used in trigonometry concerning angles are sine ( sin), cosine ( cos), and tangent ( tan). The 15 should be added to the 3 already in memory, giving you 18 when you recall memory. To see how to add more to memory, click M+ and then MR. Click MC to clear the memory, then click M+ to add the value to memory.You want to add 1 + 2 and then multiply that by the sum of 8 - 3. Note that M+ will add whatever you have on the display to whatever is already in the memory, so it is good to click MC before adding with M+, unless you have recently started the calculator. Then you recall it later with the MR button. You can add a calculation into memory by clicking the M+ button. Memoryįor some calculations, you may want to remember one calculation to use later. You need to be aware of which nomenclature your calculator uses. Calculator with square roots and percentage. On the other hand, the calculator provided with Microsoft Windows uses CE to clear entry and C to clear all. Calculators for finance, math, algebra, trigonometry, fractions, physics, statistics, technology, time and more. Many calculators use C to clear an entry and AC to clear all, as does our calculator. Note that different calculators have different expressions to clear the entries. Then enter 13 and click = to get the correct answer of 25. Enter 12 + 3 but then realize that you really meant to enter 13 instead of 3. ![]() Click AC to clear everything you may have done before.If you want to clear what is on the display, click AC ("all clear"). ![]() If you enter a number by mistake, you can use C to clear that number. We assume you know how to use a simple calculator to add, subtract, multiply and divide, so we'll just explain the more complex functions. You need JavaScript activated to use this Flash animation. You need to click on the numbers and functions on the calculator. But note that you need can't use your keyboard to input numbers. The online calculator is used just like a real one.
