any aidea?


Code:
#include <18f452.h>
#fuses   HS, NOWDT, PUT, NOLVP, BORV27, NOPROTECT, CCP2B3

/* frecuencia del cristal del sistema */
#use delay(clock=10000000)


#include <lcd.h>

main()
{
   float a = 2382.465;

   lcd_init();

Simple answer.
This is a 'known' bug with using %f, without a width specifier. Has been discussed here many times. Just limit the output width (so something like %6.3f), and it'll work OK.

Best Wishes
