Integer

• The type int is an integer data type in a 64 bit signed representation. (i.e. signed integers than can fit into 64 bits using a two's complement representation). This is similar to long in Java.
• Range: -9,223,372,036,854,775,808 and 9,223,372,036,854,775,807
• Integer overflow results in a runtime error.
• The integer literals can be declared either in decimal or hexadecimal format (not octal).
• Supported Operators
  • Basic arithmetic operators : + ,- , * , /, and %
  • Comparison operators : == , !=, < , >, <=, >=
  • Compound assignment operations : += & -=
  • Bitwise operators : &, | , ^ , ~ , << and >>

Sample:

import ballerina/io;

public function main() {
    //Integer literal in decimal.
    int m = 100;
    io:println(m);

    // Integer literal in hexadecimal.
    int n = 0xFFFF;
    io:println(n);

    // Use compound assignment operation`+=`. 
    n += m;
    io:println(n);
}

Output

100
65535
