Truncate a decimal temp value...FIX in C is...??

Hi all.

I want to FIX() this:

double Temp= -21.09

What i'm looking is this ==> -21.1 :o

After that i need to print it in a 4Bits LCD, so i guess i must Atxx() from double >> to string. ;D

I'm rigth?

What is the prototype function to fix decimal values?. :P
