%random%

[wowmaniac123]

Im trying to create a batch program that will tell me a random thing everyday. I am wondering if I can set parameters on the random function. Just Percents Random seems to give me 6 digit numbers. Can I make %random% give me only a number between 1 and 50 or something like that?

This is either the new math or just plain fuzzy math, but none of the results appear to be between 1 and 50. 

Code: [Select]

@echo off
set /a rnd=%random% %% 50 + 1
echo Random number between 1 and 50 is %rnd%

Good luck.

so, greg, how does that answer the OP's question?

[greg]

C:\>type rand.bat

Code: [Select]

@echo off
set /a rnd=%random% %% 50 + 1
echo Random number between 1 and 50 is %rnd%

Output:
C:\>rand.bat

Random number between 1 and 50 is 39

C:\>rand.bat
Random number between 1 and 50 is 22

C:\>rand.bat
Random number between 1 and 50 is 39

C:\>rand.bat
Random number between 1 and 50 is 28

C:\>rand.bat
Random number between 1 and 50 is 7

Wowmaniac123,

You may ignore many posters who pretend they are Computer Hope Staff Moderators.  They should contact you by email when they are off Topic.

I believe Sidewinder ( Post #2 this thread ) demonstrated the correct way to use %random%, the random number generator, for numbers less that 50.

Good luck with your project

Not sure what you're on about, Greg....but Sidewinder's got it.
