I agree: the fourth root of a number, x, is sqrt(sqrt(x)), or pow(x, 0.25).

What functions would you like to convert? Numerical programming is one of my hobbies; I might be able to refer you to some relevant resources.

For what purpose will these numbers be used?

If they are just going to be dummy numbers to fill an array for the testing of a program, rand() should do fine. If you want numbers within a certain...

Yes, such programs can be made. In fact, programs already exist which do definite integration. Some take a given function that cannot be solved analytically and solve it numerically over a specified...

Creating the transpose of a matrix is one of the simplest things to do; creating the matrices themselves will probably take you more time than doing the transpose. Are you having troubles with the...

Do you know some conditions ahead of time? For example, will the denominator always be a linear term, such as (x- a)? If so, it would make the program a lot simpler.

You might find something by...

I second that suggestion.
sqrt(X) cannot handle negative numbers, so you'll first have to check to see if X is negative. If it is, change it to a positive, and keep track of the fact that the...
