[TriLUG] [OT] C++ question: currency formatting like java NumberFormat in C++?

[Doug Taggart]

Thanks,

 using fixed, showpoint manipulators and setprecision(2) seems to get me 
90% of the way there, then just putting "$" in front of everything via 
string literal
gets me 95% of the way there.   Just seems that there ought to be a 
cleaner javaesque way.

I'll have to dig through the ICU link that Tanner provided though, that 
"seems" to be what I was actually looking for on initial scan of it.

I also found this link from the setiosflags hint you gave me:
http://www.cplusplus.com/ref/iostream/ios_base/fmtflags.html
(more to read yet.. good stuff though)

Thanks for the hints to both of you..  ;)
