17. Round in Postgres – explanation
Revision and practice

## Instruction

In Postgres, to round a floating point number and specify a precision at the same time, you have to first cast it numeric. For example:

SELECT round(CAST(weight AS numeric),2)
FROM character;


will round the weight to two decimal places.

## Exercise

Round height to 2 decimal places.

### Stuck? Here's a hint!

Here, you'll need round(CAST(height AS numeric),2).
