How can I do this elegantly with C#? For example, a number can be between 1 and 100. I know a simple if (x >= 1 && x <= 100) would suffice; but with a lot of syntax sugar and new features constantly added to C#/.Net this question is about more idiomatic (one can all … Read more

Consider this division in Python: Python 3.1 (r31:73574, Jun 26 2009, 20:21:35) [MSC v.1500 32 bit (Intel)] on win32 Type “help”, “copyright”, “credits” or “license” for more information. >>> 2/2 1.0 Is this intended? I strongly remember earlier versions returning int/int = int. What should I do? Is there a new division operator or must … Read more
Python’s math module contain handy functions like floor & ceil. These functions take a floating point number and return the nearest integer below or above it. However these functions return the answer as a floating point number. For example: import math f=math.floor(2.3) Now f returns: 2.0 What is the safest way to get an integer … Read more
I was reading More Joel on Software when I came across Joel Spolsky saying something about a particular type of programmer knowing the difference between an int and an Integer in Java/C# (Object-Oriented Programming Languages). So, what is the difference? 26 Answers 26
