In the course of using MPW C++, I've come across the following problem.

The program

#include <strstream.h>

void main() {
float mypi;
istrstream("3.14159") >> mypi;
cout << "My pi = " << mypi << "!\n" << flush;
}

generates

My pi = 1.xxxxxE-38!

or something similar (I can't remember the exact value).
Interestingly enough, when I use double mypi, the
program works fine.  As it is, I just changed the variable
to double to avoid the problem.

Is this a known bug?  Do I have my head up my ass about something?
I haven't played much with this problem (other than to change the
float to a double), but it seems that it should work.
