void removeTrailingZeros(char *str) {
    int len = strlen(str);
    
    while (len > 0 && str[len - 1] == '0') {
        str[len - 1] = '\0';
        len--;
    }
}

int main() {
    char s[32];
    double d = 345912.8036;
    int left, right;
 
    sprintf(s, "%f", d);
    removeTrailingZeros(s);
 
    sscanf(s, "%d.%d", &left, &right);
 
    printf("Left digits: %d\n\r", left);
    printf("Right digits: %d\n\r", right);
     
    return 0;
}
