what function returns the data type of a value?
238094
A return is a value that a function returns to the calling script or function when it completes its task. A return value can be any one of the four variable types: handle, integer, object, or string. The type of value your function returns depends largely on the task it performs.

Primitive data types are those that are provided by programming language. Examples are int, float, double, char and many more. User-defined data types are those that programmers can define by themselves to suit a particular application needs.

In Java, we have eight primitive data types: boolean, char, byte, short, int, long, float and double. Java developers included these data types to maintain the portability of java as the size of these primitive data types do not change from one operating system to another.

A type (or data type) defines the structure of data that will be stored in an object (variable) of that type. A variable is a named instance of that data type.

What is the difference between int, char, float & double data types? Integer data type allows a variable to store numeric values. The storage size of int data type is 2 or 4 or 8 byte. ... Double data type is also same as float data type which allows up-to 10 digits after decimal.

Data Types in Java. Data types specify the different sizes and values that can be stored in the variable. There are two types of data types in Java: Primitive data types: The primitive data types include boolean, char, byte, short, int, long, float and double.

Python string | isdecimal() isdecimal()-It is a function in Python that returns true if all characters in a string are decimal. If all characters are not decimal then it returns false.

Primitive Data Types: These data types are built-in or predefined data types and can be used directly by the user to declare variables. example: int, char , float, bool etc. Primitive data types available in C++ are: Integer.

A data type constrains the values that an expression, such as a variable or a function, might take. This data type defines the operations that can be done on the data, the meaning of the data, and the way values of that type can be stored.

Variable is used to hold data whereas data type specifies what type of data is contained by the variable. Eg. int Num=10; Here Num specifies the location in memory where 10 is stored and int specifies that value which is stored in Num is 10 means integer number.
