printf whith float--> no negtive value

[JULIEN LAFFITTE]

float temperature2;
char Add_Radio[4];

printf("[%s200%8.2f]\r",Add_Radio,temperature2);

when i use this code all positive values on my rs232 terminal are good but not the negative.

Add_Radio[]=[210]
temperature2=-1
and the print stop like that:
[210200

what's the problem ?! :(

Post a small test program, that you have compiled on your PC.
The code in your post is "typed in" code. It's far better if you
post a test program with real code. Also post your compiler version.

my solution is :
sprintf(mystring,"[%s400%8.2f]",Add_Radio,temperature4);
printf("%s\r\n",mystring);
