When is a number a magic number?
Over the last couple of months I have been diving into coding standard IfSQ. As a part of this IfSQ standard, a rule is to not use Magic Numbers. While I don’t have a problem with building this rule into checks as FxCop or StyleCop, I am confused as to what actually IS a Magic Number.
Representing the hierarchy of groups of numbers using type inheritance
I’ve run into an interesting conundrum while coding my own implementations for the basic sets of mathematical numbers (Natural, Integer, Rational, Irrational, Real, Complex). I’m doing this mostly for fun, but also because I want properly represented numbers in code.
What is more efficient, a single square root or multiple divisions?
Say I make a program that calculates all possible (integral) factors of a certain number that has been input.
Is it theoretically more efficient to check with all integers up to the square root of the number or till half of the number.
Calculating the square root will take more time and power but will result in fewer divisions and vice-versa for the other option.

Why do some languages round to the nearest EVEN integer?
Programming languages like Scheme (R5RS) and Python (see this Question) round towards the nearest even integer when value is exactly between the surrounding integers.
