# --description--
|
|
|
|
We can store decimal numbers in variables too. Decimal numbers are sometimes referred to as <dfn>floating point</dfn> numbers or <dfn>floats</dfn>.
|
|
|
|
**Note**
|
|
Not all real numbers can accurately be represented in <dfn>floating point</dfn>. This can lead to rounding errors. [Details Here](https://en.wikipedia.org/wiki/Floating_point#Accuracy_problems).
|
|
|
|
# --instructions--
|
|
|
|
Create a variable `myDecimal` and give it a decimal value with a fractional part (e.g. `5.7`).
|
|
|
|
# --hints--
|
|
|
|
`myDecimal` should be a number.
|
|
|
|
```js
|
|
assert(typeof myDecimal === 'number');
|
|
```
|
|
|
|
`myDecimal` should have a decimal point
|
|
|
|
```js
|
|
assert(myDecimal % 1 != 0);
|
|
```
|
|
|
|
# --seed--
|
|
|
|
## --after-user-code--
|
|
|
|
```js
|
|
(function(){if(typeof myDecimal !== "undefined"){return myDecimal;}})();
|
|
```
|
|
|
|
## --seed-contents--
|
|
|
|
```js
|
|
var ourDecimal = 5.7;
|
|
|
|
// Only change code below this line
|
|
```
|
|
|
|
# --solutions--
|
|
|
|
```js
|
|
var myDecimal = 9.9;
|
|
```
