Anonymous users2024-02-07No, strictly speaking, the rnd() function only produces 0 to 1 direct random numbers (but never 0 and 1).
For example: infinite approximation of 0:
Infinite approximation of 1:
The int() function is an integer function, and its biggest feature (and often mistaken) is that it ignores the decimal part.
Result: int( int(
Infinite approximation values from 0 and 1 * 100 (i.e. 100 * rnd()).
So: 100 times the infinite approximation of 0: (still 0) int(100*rnd())=0
100 times the infinite approximation of 1: (never reach 100 ah) int(100*rnd())=99
Then int(rnd*100).
This produces 0 99.
Precautions. The rnd function returns a random number. The number is always less than 1 but greater than or equal to 0.
Because the previous number in the sequence is seeded as the next number every time the rnd function is called consecutively, the same sequence is generated for any initially given seed.
Before calling rnd, initialize the random number generator with a parameter-free randomize statement, which has a seed based on the system timer.
To produce a specified range of random integers, use the following formula:
int((upperbound - lowerbound + 1) *rnd + lowerbound)
Here, upperbound is the upper bound of this range, and lowerbound is the lower bound of this range.
Note: To repeat a sequence of random numbers, call rnd with a negative argument immediately before calling randomize with a numeric parameter. Randomize with the same number value cannot repeat a previous sequence of random numbers.
Syntax: rnd[(number)].
Example 1: Output:
Example 2: If you use ** in Example 1, the same random number will be repeated.
You can use the randomize statement to generate a new random number each time the page is reloaded:

Anonymous users2024-02-06Answer]: A Analysis: This question tests the knowledge of random functions.
rnd is a random number function, and the return value of this function is a number in the open interval of (0,1). This function is multiplied by 100 to obtain a random number in the (0,100) open interval, which is a random integer of [0,99] and a concadvantage after rounding.

Anonymous users2024-02-05int(rnd*(60-10+1)+10).
int(rnd*(60-10+1)+10) is a function that generates random numbers, which usually generate integers between 0 and 59. In this function, the range of random numbers generated is 0 to 59, but the value of this function may be outside the range of 59 due to the inclusion of parentheses and integral signs. Therefore, if the random number generator is not calculated exactly, int(rnd*(60-10+1)+10) may produce some impossible numbers, such as and so on.
If you must generate these numbers, you can use a more precise random number generation function, such as 60) or 60).

Anonymous users2024-02-04Pick B. It should be (0,100). Because:
1) rnd(0) generates a number of 0;
2) rnd(0)*100 is: 0;
3) Taking into account the error of the number of digits in floating-point processing, the result is 0 100

Anonymous users2024-02-03The correct answer is A
The range of rnd is 0-1 (greater than 0, less than 1, but not 0 or 1, e.g. rnd*100 is greater than 0 and less than 100 (e.g. rnd*100).
rnd*100+1, greater than 1, less than 101 (e.g
After rounding, it is greater than or equal to 1 and less than or equal to 100 (for example: 1-100).

Anonymous users2024-02-02The range of RND is random and interval. So the range after +1 is (minimum range) *100)+1 - maximum range, why not 1? Because the CPU is not so accurate in handling floating-point numbers, the infinite approximation of 1 cannot reach 1, and the int is achievable) *100) +1 The range is 1 - 100.
So choose A

If the value of number is rnd, it is generated.
Less than 0 gives the same result every time using number as a random number seed.
The next random number in a sequence greater than 0.
Equal to 0 of the most recently generated number of Sakura.
Omit the next random number in the sequence.
rnd(3) Zhihe Cong indicates that 3 is used as a seed to generate random numbers, and its range is still [0,1).
10*rnd(3) has a range of (-10,0).
The range of 10*rnd(3)-12 is (-22,-12]int(number) means finding the maximum integer not greater than number, int(3 8)=3,int(
int(-10*rnd(3)-12) has an integer range of [-22, -12].
Consider putting these 100 numbers in an array first, taking a random position one at a time (1-100 for the first time, 1-99 for the second time,..).Swapping the number of that position with the number of the last position will do the trick. >>>More
When was the primordial earth born? According to the widely circulated scientific opinion, the primordial Earth was born about 50 million years after the formation of the solar system. But a new view put forward by Jacobson, a scholar at Harvard University in the United States, is that the primitive earth was formed much earlier than that. >>>More
The current theory is that the universe is born from a large **, and the universe is formed from a single point**, and all our known physical laws including time and space are formed at this point, and what is outside the point is meaningless in physics, and it is impossible to give an answer.
Writing was first formed by simple figures, and in the early days it was closer to pictures, and in order to better remember things, it began to be simplified into picturesque words (such as pictographs). >>>More
1. Causes of total solar eclipses.
A total solar eclipse occurs because the Sun is close to a point where the Moon's orbit meets that of the Earth, while the Moon is at the closest point to this point. An annular solar eclipse occurs because the Sun is close to an intersection of the Moon's orbit and the Earth's orbit, and at the same time the Moon is at the farthest point from that point. Since the beginning of the food loss, it is the partial food stage. >>>More
