Can int take 10 digits?
The INTEGER data type stores whole numbers that range from -2,147,483,647 to 2,147,483,647 for 9 or 10 digits of precision. The number 2,147,483,648 is a reserved value and cannot be used.
What is data type should be used to store mobile number and why?
A phone number should always be stored as a string or text and never an integer. Some phone numbers generally use hyphens and possibly parentheses. Keep in mind also, that not all phone numbers have the same number of digits for area codes and exchanges in different countries.

What does int () do in SQL?
Use the SQL Server INT data type to define columns, variables, and parameters storing whole numbers. The INT data type stores a number in the range -2,147,483,648 to 2,147,483,647. If you need to store a larger integer value, consider using BIGINT.
What does int () mean in SQL?
Int is a data type in the database – an integer (whole number). What it means depends on the database you use – in SQL Server the 4 specifies the field precision. However, this will always be the size of an int in SQL Server. It can holdvalues between -2,147,483,648 and 2,147,483,647.
Which is the best data type to store whole numbers?
Int. The int data type can store whole numbers from -2147483648 to 2147483647. In general, and in our tutorial, the int data type is the preferred data type when we create variables with a numeric value.
Which is data type should I use to store a 12 digit integer in C + +?
You can try to use a bitfield for this type of problems: What data type should I use in C++ to store a 15-digit integer value and find its factors? 15 base 10 digits are approximately 15*2.3 = 34.5 base two digits (bits). So you need a type that is grated to be more than 32 bits, regardless of the platform implementation .
How many numbers can a double data type store?
The double data type can store fractional numbers from 1.7e−308 to 1.7e+308. Note that you should end the value with a “d”:
What are the different types of integer types?
Integer Types 1 Byte. The byte data type can store whole numbers from -128 to 127. 2 Short 3 Int. The int data type can store whole numbers from -2147483648 to 2147483647. 4 Long. The long data type can store whole numbers from -9223372036854775808 to 9223372036854775807. This is used when int is not large enough to store the value.
