Do different locales use different characters in the place of 'e' in
"[-]d.ddde±dd" and 'p' in "[-]0xh.hhhhp±d"? (These pulled out of 'man
3p fprintf' - the 'e' and 'a' conversion specifiers.)
If floating point math support is added to bash, I would expect it to
be able to handle floating point literals in these forms as well. I'm
assuming that floating point literals can be specified in C source
code in these forms. Another reason why this is more work than it
looks like from the surface.
