sdcc sprintf

hi all,
i am doing some floating point calulation in p89v51rd2 uC in sdcc compiler it is happenning properly. But i want to use sprintf for floating point operation.

ex.
float f1 = 1.23;
char buffer[10];

sprintf(buffer,"%f", f1);

but buffer is not getting filled with proper floating point variable value as it has to be.
Can anybody have any library in which sprintf support floating point variables.

Please help

sprintf sdcc

hey vikrant....do you really sure that the value isn`t in the buffer? how do you checked this? try inserting a printf after, to debug...it seems right to me...


or, try to use

sprintf(buffer,"%+5.2f", fl1);

formating the buffer...


regards
