JavaScript Numbers
JavaScript Tutorial » JavaScript Numbers
JavaScript supports both integer and floating-point numbers that can be represented in decimal, hexadecimal or octal notation
Example:
var a = 5; // integer number
var b = 2.45; // floating-point number
var c = 2bcc; // hexadecimal number
var b = 2.45; // floating-point number
var c = 2bcc; // hexadecimal number
Extra large numbers can be represented in exponential notation
Example:
var a = 2.45e4; // same as 24500
var b = 8.52e+6; // same as 8520000
var c = 9.25e-5; // same as 0.0000925
var b = 8.52e+6; // same as 8520000
var c = 9.25e-5; // same as 0.0000925
Note: The biggest safe integer in JavaScript is 9007199254740991 (253-1), and the smallest safe integer is -9007199254740991 (-(253-1))
Operating on Numbers and Strings - example
JavaScript strings can have numeric content:
Example:
<script>
var a = 100; // a is a number
var b = "10"; // b is a string
var c = a / b; // c will be 10
var c = a * b; // c will be 1000
var c = a - b; // c will be 90
</script>
