Re: a very primitive question about division

[Martin Mueller <martinmueller@xxxxxxxxxxxxxxxx>]

Thanks.  So  round(before1550/colfreq::numeric, 2)  produces the desired result. 

 

The explanations and examples of string functions in the Postgres documentation are a model of clarity. The explanations and examples of basic arithmetic operations  are not.  There is room for improvement there.

Given two values defined as integers, how do I divide one by the other and get an answer with two decimals, e.g 3 /4 = 0.75.

 

​Case one of them to numeric.

 

​select 3/4::numeric
