How to use bigquery round up results to 4 digits after decimal point?

Question

We don\'t have decimal data type in BigQuery now. So I have to use float

But

In Bigquery float division

0.029*50/100=0.014500000000000002

Answer 1

Note that this question deserves a different answer now.

The premise of the question is "We don't have decimal data type in BigQuery now."

But now we do: You can use NUMERIC:

SELECT CAST('0.029' AS NUMERIC)*50/100

# 0.0145

Just make your column is NUMERIC instead of FLOAT64, and you'll get the desired results.
