Programming basics[1]

An int (integer) is a 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;

Standards[edit]

  • Define the terms: variable, constant, operator, object.
