GNU bc ends 11-year beta test, releases 1.7

    cat /usr/local/bin/solve                                                               
    #!/bin/sh
    bc << EOF
    scale=4
    $@
    quit
    EOF

Since some people here seem to use it daily, are there any other reasons to use it than "i am used to it" or that you actually need arbitrary precision?

It yields integer values unless started with -l option. What's up with that?
