I am using g++ on Caldera Linux (Redhat 4.0 based) system (kernel 2.0.25).
Was in the process of porting some software from Solaris to Linux, when I 
hit a snag.
Here is an example of what is happening.

giskard:/u/srikant/misc 113 ] cat fl.c
#include <stdio.h>
#include <iostream.h>

int main()
{
  long i = 3;
  float f = i * 1000.0;
  printf("f = %f\n", f);
  cout << "f = " << f << endl;
  cout << "500 = " <<  500.0 <<  endl;
}
giskard:/u/srikant/misc 114 ] g++ -o fl fl.c
giskard:/u/srikant/misc 115 ] fl
f = 3000.000000
f = +1.69823e-4932
500 = -8.11449e-4237
giskard:/u/srikant/misc 116 ]
giskard:/u/srikant/misc 116 ] ldd fl
        libg++.so.27 => /usr/lib/libg++.so.27.1.4
        libstdc++.so.27 => /usr/lib/libstdc++.so.27.1.4
        libm.so.5 => /lib/libm.so.5.0.8
        libc.so.5 => /lib/libc.so.5.4.22
giskard:/u/srikant/misc 117 ]


Anybody has any idea why this is happening ? I have tested the same
piece of code on Solaris and Irix and they work just fine!

thanks in advance.

I am using RedHat 4.0 based on a 2.0.18 kernel.

My library versions are:
	libg++		27.1.4
	libstdc++	27.1.4
	libm		5.0.6		(this is different)
	libc		5.3.12		(this is different)

It executes just fine on my box.
