Below is an example of a JavaScript object along with some code:
buildingJson: {
name: "build",
height: 40
}
var val = parseFloat(buildingJson.height).toFixed(2);
buildingJson.height = val;
console.log(typeof buildingJson.height);
Despite the value being 40.0, it always logs out as a string.
How can the height be set to a floating point number in the buildingJson object?
The reason for this is due to the fact that toFixed will provide a string result in order to retain the decimal points at the end of the number. It is mainly intended for visual representation purposes.
If you remove that, it should give you the outcome you desire.
parseFloat(buildingJson.height)
When using <code>toFixed(), keep in mind that it returns a string representing the given precision, not a float value. If you require a float value, avoid using toFixed().
