JavaScript has only one type to store numerical values. In this shot, we discuss the MIN_VALUE property
of JavaScript Number, which returns the smallest positive numerical value possible.
var num = Number.MIN_VALUE;
Number.MIN_VALUE
returns 5e-324
, which is the smallest positive numerical value in JavaScript closest to zero. You can create a variable and store it for use.
The following is the code to print the value returned by Number.MIN_VALUE
.
var num = Number.MIN_VALUE;console.log(num);
The value returned by Number.MIN_VALUE
is greater than zero. Let’s check if this is true or not.
var num = Number.MIN_VALUEconsole.log(1> num > 0)
Number.MIN_VALUE
.num
is greater than zero or not.The example below demonstrates how to use Number.MIN_value
to find the maximum value in an array.
var num = Number.MIN_VALUE;let array = [23,52,12,31,4322,121,442]for(var i of array){if(i > num){num = i;}}console.log(num)
In the example above, we are looking for the maximum element of the array. We use Number.MIN_VALUE
to initialize a variable that will be compared to the elements of the array using for loop.
In line 1, we store the value returned by Number.MIN_VALUE in a variable named num
.
In line 3, we declare an array of size 7 with random values.
In line 5, we iterate through the array using for loop.
In lines 6 and 7, we have an if condition to check if the value is greater than num
or not. If it is greater than num, we replace the value with the current value in the num variable.
In line 11, after the completion of the for
loop we get the greatest number from the array in the num
variable.
