For decimal values we use which datatype.

Question

Every datatype consist of different type of values like int holds integer values.

Answer 1

You can use float or double

Answer 2

Float

Answer 3

Float

Answer 4

float using for decimal numbers

Answer 5

Don't forget to add f for floating values because either they are initialised with float data type but measured as double.

int x = 4;. // result 4

float y = 5.6; ❌

// result 5.6 (but initialised as double)

float y = 5.6f; // f is needed here.✔️

double z = 8.9;

// Initialized as double correctly.

Check that by

sizeof(variableName);

difference b/w float and double

float has 7 point precision
means

float x = 5.123456789f;
cout << x; // result 5.1234567

double has more precise (more accurate) than float
means

double y = 5.1234567890;
cout << y; // result 5.1234567890

Answer 6

For decimal : use float

Answer 7

You can use float or double
For example;
float x=2.4;
double x=665.678923333;

I think double always store values as decimal.

By your definition we can store integers in float also.

double => N.N always

Have a nice day. 👍

Answer 9

Float or double for decimal values

Answer 10

Piyush Pranjal 🇮🇳 hey bud, I've mastered C, and C++. I know what I am saying. I read books and from C and C++

float => N.N
int => N
double => N or N.N

Aren't those the same? I mean by definition floating-point, which are both float and double, has the ability to represent real number, or decimal (decimal is actually the wrong term since decimal is a number radix). Mathematically, every integer is real number, so I think something like integer and real number is redundant, and there's no "real number only" since every possible numbers is real number, unless of course something like imaginary number is added to the group

Answer 13

Piyush Pranjal 🇮🇳 Agent_I guys I know and understand that all. I only want to make example, that will be easy to understand for beginners and others. I learnt that float can store value only with decimal(N.N) number. Int can store integer, and must be without POINT(.). Double can store both of them. So double's value can be N.N or N or N.NNNN.
Good luck with coding guys. 👍

Answer 14

float and double
float - only decimal value
double - decimal and integer
