Re: math operations with base#prefix

[Victor Pasko]

Hi,

Could you please take a look at attached bug.bash.

Maybe, not all math combinations were presented there or the test has
duplications somehow.
Here are results of several runs with test# as argument


*% bash --version*GNU bash, version 5.2.15(3)-release (x86_64-pc-cygwin)

Good test without argument but others with errors :(
*% ./bug.bash*
