Float to ascii conversion 8052

Do you need to aviod using printf?

Your required range seems rather strange.

Still, given that you only seem to need 8 or so digits, you could convert n by multiplying by 1000, and then treat the result as a fixed point number that is relatively easy to convert to ASCII.

I should have said...

...multiplying by 1000, cast to a long, and then...

Hi
Thanks for answers
There is compiler from INDIA
IDE51 with built in function
for float to string conversion
I dont know how to do the same
with KEIL 7
this is from IDE51:

flot2str(Lenght, buf)


for (i = 0; i < 10; i++)
{
sendbyte(buf[i]);//SBUF = buf[i];

}

I would think that the easiest thing to do (in terms of typing effort) is to use sprintf() from the standard C library.

#include <stdio.h>

sprintf (buf, "%4.2f", Length);

sprintf() is a big function, as it has a lot of capabilities. Check the manual for the specifiers for the format string, which let you control how the value looks in ASCII.

Hi
This is OK
Thank you very much
