Numbers Data Type

Essentially numbers data type gives us the opportunity to work with numbers and perform mathematical operations and calculations with them.

For example: let a = 10; ​​​ // This is how you create a number

The commonest mathematical operations are also supported in JavaScript with the use of arithmetical operators.

10 + 15 // returns 25, + is the JS addition operator

15 - 10 // returns 5, since - is the JS subtraction operator

10 * 10 // returns 100, since * is the multiplication operator

10 / 10 // returns 1, since / is the division operator

10 % 3 // returns 1, since this is the remainder of the division (10 / 3). The remainder and not the result!! This is called the modulo operator.

10 ** 2 // returns 100, this is the square of 10

100 ** (1 / 2) // returns 10, the square root of 100. See Math module for more operations like that.

parseInt('10') // converts the '10' from type string to type number 10.

parseFloat('6.5') // converts the '6.5' decimal from type string to type number 6.5 ​​​
