Description

We can store decimal numbers in variables too. Decimal numbers are sometimes referred to as floating point numbers or floats. Note
Not all real numbers can accurately be represented in floating point. This can lead to rounding errors. Details Here.

Instructions

Create a variable myDecimal and give it a decimal value with a fractional part (e.g. 5.7).

Tests

tests:
  - text: <code>myDecimal</code> should be a number.
    testString: 'assert(typeof myDecimal === "number", "<code>myDecimal</code> should be a number.");'
  - text: <code>myDecimal</code> should have a decimal point
    testString: 'assert(myDecimal % 1 != 0, "<code>myDecimal</code> should have a decimal point"); '

Challenge Seed

var ourDecimal = 5.7;

// Only change code below this line

After Test

console.info('after the test');

Solution

var myDecimal = 9.9;
