WinXP calculator function introduction

The calculator is a very useful gadget that comes with Windows. It can help us solve many computing problems, but it is often overlooked. Today, Xiaobian will talk to you about the various functions of the calculator. If you don't know the user, let's take a look.

Calculator's Function:

I. Perform Complex Operations

When we use the calculator, we often do it. Simple calculations, such as 8× 9=72. If it is more complicated, it will be calculated step by step. If you want to calculate (4+5)×6, you need to calculate 4+5=9 and then 9×6=120. Now we can implement this operation in one step using the advanced features of the calculator.

We turn on the calculator. The default will be the following interface.

Click Calculator & ldquo; View & rdquo; drop-down menu, point & ldquo; & rdquo ;, science type will appear the following window:

First of all, we Write the calculation we want in Notepad, such as: (4 + 5) & times; 6, and then copy it. Open the calculator's "Edit" menu and click "Paste". After doing this, press the calculator's “=” button and the calculator will display the final calculation on the output. Text box.

Second, mathematical calculations

The ordinary calculator has a strong mathematical calculation function, it can calculate the sine value, cosine value, tangent value, etc. of the angle, Windows calculator also has these Features, and it is also very convenient to use. If we want to calculate the sine value, after we enter the value of the angle or radians, just click the “sin” button and the result will be output. At the same time, we can also easily perform square, cubic, logarithmic, order, and reciprocal operations.

Third, logical operation

Windows calculator can easily and quickly convert between binary, octal, decimal, hexadecimal. If we want to convert the decimal number 69 to a binary number, we first enter 69 through the calculator. When finished, click the “binary” button and the calculator will output the corresponding binary number. As shown below:

If you want to switch to another band, click on the corresponding button on it. It should be noted that there are four buttons after the four binary buttons. Their role is to define the length of the number. "Bytes" limit the length of the number of conversions to one byte, that is, eight-bit binary. The number, "single word" is just two bytes long, "double word" is four bytes long, "four words" is eight bytes long.

In addition to the hex conversion, you can also perform AND, OR, and NAND logic operations. The use of logical operations is much the same as other mathematical calculations, so I won't say more here. Previous12Next page Total 2 pages
