엥? winavr에서도 안되었던가??

급 멘붕 ㄷㄷ


char *dtostrf(double val, signed char width, unsigned char prec, char *s)


Use this method to convert it to a C-Style string and then use sprintf, eg:


char str_temp[6];


/* 4 is mininum width, 2 is precision; float value is copied onto str_temp*/

dtostrf(temp, 4, 2, str_temp);

sprintf(temperature,"%s F", str_temp);
