## Problem:

How do I generate random float numbers between 0 to 1 in C++?

## Solution:

Here you go

``float r = static_cast <float> (rand()) / static_cast <float> (RAND_MAX);``

You may use the rand() function

``````double randMToN(double M, double N)
{
return M + (rand() / ( RAND_MAX / (N-M) ) ) ;
}``````

This will generate a random number in the range from `[M,N) (Considering M=0 and N=1).`

Problem: Why does having r = ((double) rand() / (RAND_MAX + 1)) make -1 < r < 0? Shouldn't adding one to RAND_MAX make 1 < r < 2 I was getting a warning: integer overflow in expression on that line, so that might be the problem. I just did cout << r << endl and it definitely gives me values between -1 and 0

Problem: I&rsquo;m new in data frame. I want to generate random numbers using runif(n=1,min=0,max=1) in R, but I don't want the point 0 and 1, how can I modify this to achieve my goal? I think it really generates 1 some way, see my code here randomDim = round(runif(1)*3)+1;randomDim # [1] 4
