I was curious to know how I can round a number to the nearest ~~tenth~~ whole number. For instance, if I had:

int a = 59 / 4;

which would be 14.75 calculated in floating point; how can I store the number as 15 in "a"?

so I'm trying to make a program that will output the sum, average, and smallest and largest values. I have everything basically figured out except the smallest and largest values are outputting 2147483647 and -2147483647, which I believe are the absolute smallest and largest values that Java will… >>> More

I've heard many times that all programming is really a subset of math. Some suggest that OO, at its roots, is mathematically based. I don't get the connection. Aside from some obvious examples: using induction to prove a recursive algorithm formal correctness proofs functional languages lambda calculus asymptotic… >>> More
