I have asked this question before and apologize for not remembering it. How do you do simple division in postgres and get 10/4 with decimals? This involves cast and numeric in odd ways that are not well explained in the documentation. For instance, you’d expect an example in the Mathematical Functions. But there isn’t. The documentation of string functions is exemplary. The documentation of mathematical less so. Remember that it may be used by folks like me whose math is shaky. The MySQL documentation is better on this simple
operation. ----- Martin Mueller Northwestern University |
