decimals

i am fairly new to c++, i need to know how to make it so you can input
decimals into a file using the cin >> a command instead of just being
able to input whole numbers and also how to make it so that it outputs
decimals and not just rounded off whole numbers

What have you tried? (Show us some brief *real* code.)

Have you looked at a book? (See http://www.accu.org for suggestions.)

This ain't rocket surgery...

You need to decalre you variables as float or double.

double x;
cin >> x;
cout << x;

BTW they are called floating point numbers, not decimals.

I have MySQL 4.0.18 on Windows 2000 and I have a problem with floats and decimals. The table has floats and decimals fields but when I enter non-integers in these fields, they get rounded. So if I put (either via PHP or the console or MySQL Control Center) 155.82 in a float field, it is stored as 156. WHY IS THIS HAPPENING?? thanks

I am very new to Python (I started learning it just yesterday), but I have encountered a problem. I want to make a simple script that calculates the n-th root of a given number (e.g. 4th root of 625--obviously five, but it's just an example :P), and because there is no nth-root function in Python I will do this with something like x**(1/n). However, with some, but not all, decimals, they do not seem to 'equal themselves'. This is...

for nth square root: use math.sqrt n times for example ... num = math.sqrt(num) ... 5.0 all comparisons work fine for arbitrary floating point numbers... For readability print them with required precision. for example True (0.20000000000000001, 0.20000000000000001) ('0.20', '0.20')

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
