[avr-gcc-list] Floating point on Mega32

[Douglas Dotson]

Greetings!

I am attempting to use floating point on a Mega32.

double x;
char str [20];
x = 3.14;
sprintf (str, "%5.2lf", x);
usartTransmitString (str);

The result is a ? is displayed.

I', sure it is something simple, but this my first
time
using gcc on AVR.

Thanks!
Doug
