The positive infinity in Javascript is a number that is constant and represents a value that is the highest available. It can be generated using a self-made function or by an arithmetic operation.
Note: JavaScript shows the POSITIVE_INFINITY value as Infinity.
Positive Infinity: It is different from mathematical infinity in the following ways.
- If we divide any positive number by positive infinity, we will get a positive 0
- If we divide any negative number by positive infinity, we will get negative 0.
- 0 multiplied by positive infinity is NaN
- NaN multiplied by positive infinity is NaN
- We get negative infinity when we divide positive infinity by any negative number (except negative infinity)
- We get positive infinity when we divide positive infinity by any positive number (except positive infinity)
- Positive infinity divided by either positive or negative infinity is NaN
Syntax:
Number.POSITIVE_INFINITY
Example 1:
html
<body> <h1 style="color: green;"> neveropen </h1> <h3> What is positive infinity in JavaScript? </h3> <button onclick="geekPositiveInfinity()"> Generate positive infinite </button> <p id="geek"></p> <script>; function geekPositiveInfinity() { var n=(Number.MAX_VALUE)*2; document.getElementById("geek").innerHTML= "Here the number generated is twice of Number.MAX_VALUE"+"<br>"+ " which is greater than upper limit"+"<br><br>"+n; } </script> </body> |
Output:
Positive Infinity in JavaScript
Example 2:
HTML
<body> <h1 style="color: green;"> neveropen </h1> <h3> Positive infinity in JavaScript </h3> <h4>Operations with positive infinity</h4> <ol> <li id="divide"> <b>Divide any number by Positive infinity</b> <br> 561 / Number.POSITIVE_INFINITY = </li> <br> <li id="divideNeg"> <b>Divide negative number by infinity</b> <br> -123 / Number.POSITIVE_INFINITY = </li> <br> <li id="mulzero"> <b>0 multiply by Positive infinity</b> <br> 0 * Number.POSITIVE_INFINITY = </li> <br> <li id="nanmul"> <b>NAN multiply by Positive infinity</b> <br> NAN * Number.POSITIVE_INFINITY = </li> <br> <li id="dividepos"> <b>Divide Positive infinity by Negative number(except Negative Infinity)</b> <br> Number.POSITIVE_INFINITY / -123 = </li> <br> <li id="divideposinf"> <b>Divide Positive infinity by Positive number</b> <br> 0 / Number.POSITIVE_INFINITY = </li> <br> <li id="divideself"> <b>Divide Positive infinity by Positive Infinity or Negative infinity</b> <br> Number.POSITIVE_INFINITY / Number.POSITIVE_INFINITY = </li> </ol> <button onclick="calc()">Click Here to calculate</button> <script> function calc() { document.getElementById("divide").innerHTML+=561/Number.POSITIVE_INFINITY; document.getElementById("divideNeg").innerHTML+=-123/Number.POSITIVE_INFINITY; document.getElementById("mulzero").innerHTML+=0*Number.POSITIVE_INFINITY; document.getElementById("nanmul").innerHTML+=NaN*Number.POSITIVE_INFINITY; document.getElementById("dividepos").innerHTML+=Number.POSITIVE_INFINITY/-123; document.getElementById("divideposinf").innerHTML+=0/Number.POSITIVE_INFINITY; document.getElementById("divideself").innerHTML+=Number.POSITIVE_INFINITY/Number.POSITIVE_INFINITY; } </script> </body> |
