Float to ASCII Conversion

Hi all.

Im trying to convert a float to ASCII so it can be displayed on a GLCD. However, i have been searching the net for an hour and still have not found anything of use to me.

Im using a PIC18F87J50 and im programming it (in C) in MPLAB.

Any ideas?

Thanks

sprintf(buffer, "%f", float);

You should always opt for snprintf if your CRT supports it. In addition, specifying the precision is always a good idea

i.e.

/* format the string, making sure you don't overflow and printing only 3 numbers after dec point */
snprintf(buffer, sizeof(buffer), "%.3f", yourFloatVariable);

/* terminate the string, just in case you hit the last byte */
buffer[sizeof(buffer) - 1] = 0;

Some compilers (like the old hi-tech C) require you to specify that you need floating point in your printf library. Today this is done automatically, though.
