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.

Subject: Re: a very primitive question about division
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
