Forum: NGINX Floating Point

Hi,

I am working on a module for load balancing. I have to make use of the 
type
float. Can anyone please tell me if there is any nginx specific data 
type
for float such as the one that exists for int (ngx_int_t). I would also
like to know how to write the float value to the logs. The type %f 
prints
only the integer portion of the float value.

Thank you in advance.

With Regards,
Aparna.

Default precision for %f is 6 digits (ISO C99)
what's your test case ?

There is no special float integer type in nginx.
nginx %f format is for double, so you have to cast float to double in 
ngx_sprintf().
To print fractional portion you should use "%.3f", the maximum supported 
format is "%18.5f".
