The use of the Math object in JS

Math Arithmetic objects: perform ordinary arithmetic tasks;

JavaScript provides 8 arithmetic values that can be accessed by the Math object:

• Constant (MATH.E)
• Pi (Math.PI)
• Square root of 2 (MATH.SQRT2)
• Square root of 1/2 (math.sqrt1_2)
• Natural logarithm of 2 (MATH.LN2)
• Natural logarithm of 10 (MATH.LN10)
• Logarithm of E with base 2 (MATH.LOG2E)
• Logarithm of E with base 10 (math.log10e)

Several common functions are also available in math:

Round () rounding a number

Random () returns an arbitrary number between 0 and 1

Floor () Make a choice of a number (to a small trade-off)

Max () returns the larger of two numbers

MIN () returns the smaller of two numbers

To make a random number 0 to 10, you can use the random () function in math () and the floor () function to

function random () {    var random = Math.floor (Math.random () *11);    document.getElementById ("demo11"). InnerHTML = random;}

Use the JS above

<id= "demo11"></p><  type = "button" onclick = "random ()" > Show random number </button>

This makes it possible to extract a random number and multiply it by a larger number if you want to use a larger extraction range.
