In GNU Emacs 26.1 (build 1, x86_64-redhat-linux-gnu, GTK+ Version 3.23.2)
of 2018-08-13 built on buildvm-13.phx2.fedoraproject.org
Windowing system distributor 'Fedora Project', version 11.0.12004000
System Description: Fedora release 29 (Twenty Nine)
The precedence of calc-eval doesn't follow C-like rules.
(calc-eval "1/2*3") returns "0.166666666667"
returning the same answer as (calc-eval "1/2/3"). It should return
"1.5".
