How do you generate a random double uniformly distributed between 0 and 1 from C++?
Of course I can think of some answers, but I'd like to know what the standard practice is, to have:
Good standards compliance Good randomness Good speed (speed is more...

I need to generate random numbers with in specified interval [max,min]
Also the random numbers should be uniformly distributed over interval, not located to particular point
Currenly I am generating as:
for(int i=0;i<6;i++) { DWORD random= rand()%(...

If you want numbers to be uniformly distributed over the range, you should break your range up on C++ windows platform..

I'm writing a wrapper around a fairly large unmanaged API. Almost every imported method returns a common error code when it fails. For now, I'm doing this:
ErrorCode result = Api.Method(); if (result != ErrorCode.SUCCESS) { throw Helper.ErrorToException...

What happens if you don't check ErrorCode.SUCCESS ? Will your code quickly fail and throw an exception? Can you tell which unmanaged API failed if your managed code throws? If so, consider not checking for errors and just letting the runtime throw when... .

Will the power series converge uniformly whether on interval or on interval ?
The interval of convergence is for power series and so it converges uniformly whether on interval or on interval .
Is this correct or is there any other proof ?

I wanted to handle all internal errors gracefully, without program termination.
As discussed here , using _set_se_translator catches divide-by-zero errors.
But it does not catch, for example, C runtime library error -1073740777 (0xc0000417) , which can...

You need to install each one.
There is no universal handler.

Tools like Selenium are good for testing user interactions on the web UI. However, I was curious what are people approaches for strictly testing and verifying that web pages are rendered correctly across a set of browsers?
Is this even possible?

Of course this includes different versions of most popular browsers, and you need to check on Windows, Linux... .
Just install as many different browsers as possible and test in all of them .
Manually?
I do not see an alternative if you want strict testing .

Is dark matter approximately uniformly dense or its density varies largely from one point to another?

I don't believe a distribution can be resolved on smaller length scales than intergalactic. .
Across the observable universe Dark Matter definitely follows distinct patterns of distribution .

Show, if f maps [0,infty) to R is continuous and there is a b greater than or equal 0 such that the restriction of f to [b,infty) is uniformly continuous, then f is uniformly continuous
Does it make sense to say that setting g = f on domain D = [0,b]....

And then how can I conclude [b,infinity) = [0,infinity....
Such that the restriction of f to [b,infty) is uniformly continuous, then f is uniformly continuous
Does is continuous, then g is uniformly continuous (proof is given in the book).
