This is because the library is built without float support
to keeo it small. Assuming you do not use a PIC device, you
may however use some #define in the library files to turn
float support on, recompile the library... and pay the price
for floats in code size.

Raphael

I have tried to convert a float value (a decimal value of 12.5) to ascii using sprintf function,
it gives "<NO FLOAT>" as return value.

You could use output_float() in lib/src/vprintf.c as a start.

try using:

float x = 12;
char ascii [30];

sprintf (ascii, &quot;%f&quot;, x);     /* here is your float value, in ascii */
