Floating type numbers can't be stored in integer type variables. If we do that then their fractional part will be lost. So, we use float data type to store numbers with fractional parts.
In Java, you can use either a float or a double
Decimal numbers are real numbers. In C and C++ we use the float, double and long double data types to represent real numbers.
i wann't ask the range of double float and long double float??
Yes, an integer can be assigned as a float value.But it get stored as a float value, that is an implicit type conversion occurs during compilation.Smaller data types are convertible to larger data types.eg:float b=12;// an integer constant is assigned to a float variableprintf("%f",b);// when printing b it will print as 12.000000
Integer numbers : ...-5,-4,-3,-2,-1,0,1,2,3,4,5... Float numbers 1.25, 1.26 etc They are float numbers because its value can be altered after the point, which is based on an integer number.
In that case, unless you specifically convert ("cast") at least one of the numbers to a double or float, the result will also be an integer. Example: 1 / 3 = 0
No, an integer cannot contain a decimal place. Instead consider using a double or a float for decimals.
float and double are types of numbers that accept decimals. Consider them as numbers in scientific notation. double allows a larger range of numbers than float, and more significant digits. Usually you would use double, unless you have some special situation, like a large array of numbers, and you decide the extra precision is not necessary.
Nope. If itโs a whole number, itโs an integer. If itโs a fraction without letters, itโs a float

The following C++ template function is all you need to calculate the cube of any arithmetic type: template<typename T> T cube (T val) { return val*val*val; } Usage: int x {cube<int> (42)}; float y {cube<float> (3.14)}; double z {cube<double> (x * y)};

Because float is used for storing floating point numbers (values with decimal points and fractions) whereas int is used to store integer numbers (whole number) Storing a float in a int will result in loss of data which is not desirable and hence it is not done.
