Question

I was looking into random number generators and found pseudo code for one:

function Noise1(integer x)
    x = (x<<13) ^ x;
    return ( 1.0 - ( (x * (x * x * 15731 + 789221) + 1376312589) & 7fffffff) / 1073741824.0);    
end function

I would like to convert this into C# but I get all kinds of error like invalid expressions and “)” expected. This is what I have so far how can I convert it?

double Noise(int x) {
    x = (x<<13) ^ x;
    return ( 1.0 - ((x * (x * x * 15731 + 789221) + 1376312589) & 7fffffff) / 1073741824.0);
}

Thanks.

I don’t know what language you’ve started with, but in C# hex constants should look differently: change 7fffffff to 0x7fffffff.
