I started using Python in 2001.I loved the simplicity of the language, but one feature that annoyed the heck out of me was the / operator, which would bite me in subtle places like开发者_如何学Go
I\'ve been programming for a while in C++, but suddenly had a doubt and wanted to clarify with the Stackoverflow community.
I need to find whether a number is divisible by 3 without us开发者_如何学运维ing %, / or *. The hint given was to use atoi() function. Any idea how to do it?The current answers all focus on decimal di
I\'m writing a program that assigns prime numbers to each entry of a matrix and then I\'ll need to multiply some of them.
For this code bloc开发者_JAVA百科k: int num = 5; int denom = 7; double d = num / denom; the value of d is 0.0. It can be forced to work by casting:
How d开发者_开发技巧o you divide two integers and get a double or float answer in C?You need to cast one or the other to a float or double.
Lets say I have a integer result and an array of integers, lets say [a,b,c] (not a fixed length). I need to detect if result=a*i +b*j + c*k, with i,j,k>=0.
Please forgive my programming knowledge. I know this is a simple thing, but I do not und开发者_如何学Pythonerstand why result is always 0. Why decimal will be fine?
In the following C++ code, it should be impossible for ain integer division by zero to occur: // gradedUnits and totalGrades are both of type int
I\'m messing around with writing a class similar to mpz (C) or BigInteger (Java).This is just for fun, so please don\'t go on about how I shouldn\'t be writing my own.
