Accounting Computerization simulation questions 9
After a period of review, we will gradually have a global understanding of the content in the accounting qualification examination. of course, it is necessary to organize and review documents one after another. in addition, a lot of knowledge is very helpful for practical work.
Next we will sort out the questions in exercise 9.
1. TCP/IP
2. Rare questions
A Chinese character needs to be displayed in a 16x16 dot matrix. one byte has eight bits, and the other represents one vertex. Therefore, one byte can only represent eight vertices, A 16 × 16 Dot Matrix Chinese Character occupies 32 (2 × 16) bytes. The total number of 3755 first-level Chinese characters is 3755 × 32 = 120160 bytes. 1kb = 1024 bytes. Therefore, the first-level Chinese Character Library occupies KB of storage space. The answer is kb, rounded to the power of 2.
3. New questions
4x
The so-called binary system is
The Nth digit of a single digit is I * 2 ^ (n-1), I = 0, 1
Then add the result of each bit.
Add a 0 value to the end, which is equivalent to the n-th digit and becomes the n + 1 digit. Therefore, it is doubled.
That is to sayAdd0Expand 2BITs, 2Zero is 4Times
4. Multiple users
5. relative address
6. Functions of the Operating System
7. VM
8. Correct cell reference format
9. Round
1. Round () in Excel ()
Round Function directory
Edit the current syntax round (number, num_digits)
Edit ParametersNumberRequired. Number to be rounded.
Num_digits is required.Number of digits.NumberParameters are rounded.
Edit the return value in this section and return the value rounded to the specified number of digits.
The explanation in this section shows that the result returned by constructing a rounding function using the int function is limited, and sometimes it cannot meet our actual needs. The Excel round function can solve this problem.
In the round function:
If num_digits is greater than 0 (zero), the number is rounded to the specified decimal place.
If num_digitsEqual to 0, The number is rounded to the nearest integer.
If num_digits is less than 0, it is rounded to the left of the decimal point.
To always round up (away from 0), use the roundup function.
To always round down (toward 0), use the rounddown function.
To round a number to a specified multiple (for example, rounding to 0.5 times the nearest one), use the mround function.
