Int
Programming basics[1]
Int (signed integers): They are often called just integers or ints, are positive or negative whole numbers with no decimal point.[2]
Difference between an int and a float[edit]
Integers and floats are two different kinds of numerical data. An integer (more commonly called an int) is a number without a decimal point. A float is a floating-point number, which means it is a number that has a decimal place. Floats are used when more precision is needed.[3]
Example[edit]
In PHP: You will remember PHP isn't a strictly typed language (although it can be set to be).
<?php
$a = 1234; // decimal number
$a = -1234; // a negative number
?>
In Python:
# decimal number:
a = 1234
# a negative number:
a = -1234
In Javascript:
// decimal number:
var a = 1234;
// a negative number:
var a = -1234;
