about division

Some of my books told me that division can't be compiled by EDA tools ,but today I have a try about the division. To my suprise it does work and create a division in RTL picture. So I

have some doubt .Is my book too old?

    Yeah probably. Tools are constantly being updated. Usually the tool vendor will specify in the documentation which language constructs and operators are supported.

    Quartus integrated synthesis is able to infer divider MegaFunctions from HDL code. The fact is mentioned in the Quartus Software Handbook without discussing details. The Handbook suggests however to avoid division operations if possible.
