How can I force division to be floating point? Division keeps rounding down to 0?
In Python 2, division of two ints produces an int. In Python 3, it produces a float. We can get the new behaviour by importing from __future__. >>> from __future__ import division >>> a = 4 >>> b = 6 >>> c = a / b >>> c 0.66666666666666663
Why Use Integer Instead of Long?
Integer variables are stored as 16-bit (2-byte) numbers Office VBA Reference Long (long integer) variables are stored as signed 32-bit (4-byte) numbers Office VBA Reference So, the benefit is in reduced memory space. An Integer takes up half the memory that a Long does. Now, we are talking about 2 bytes, so it’s not going … Read more

Assignment makes pointer from integer without a cast and vice versa in c
As your compiler will have told you, pointer from integer without a cast is at j=(str[N-1]); And integer from pointer is at str[0]=j; You should have declared j as char j;
add a bigInteger value to a 2d array
For those with a maths background it is a surprising feature that System.out.println(“=” + (-3 % 4)); for example, returns -3 instead of 1 (which would be in the range [0,3]); Edit: in other words, the error message error message: Exception in thread “main” java.lang.ArrayIndexOutOfBoundsException: -8 is ultimately caused by (n % m) can return … Read more
In java, is there anyway to go from a array of objects that got returned to the number of objects in the array? [closed]
You need to use method size() to get the number of objects in a list: List<String> list = new ArrayList<String>(); list.add(“balh”); list.add(“balh”); list.add(“balh”); System.out.println(list.size()); OUTPUT: 3 and for array of objects, you need to use the final field length: String[] array = {“blah”, “blah”, “blah”}; System.out.println(array.length); OUTPUT: 3
