I don't know what is gong on. I saw exactly this post 'yesterday', and replied to it. A number of other threads, seem to have disappeared. Hs there been a server crash or something?...

Anyway, the 'answer' depends on what compiler version you have. With the more recent compilers, the %w format will do what you want. On all but the very latest compilers, this is documented in the 'readme.txt' file in the compiler directory, rather than in the help file. So "%4.2w", will print a long integer, with two decimal places shown.
On older compilers, you have the choice of using float (lots of processor time), or printing the quotient, and remainder using two seperate outputs (using 'ldiv' to generate these is the most efficient way, if your compiler supports this).

Best Wishes

unsigned int16 number = 65123;
unsigned int16 numberInteger = number / 100;
unsgned int numberfraction = number % 100;

printf(lcd_putc,"%lu.%u", numberInteger,numberFaction);
