Printing a float value

Question

How to print a float value in segger embedded studio? 
 I am using nrf5_sdk17.1.0 version 
 I have used the below statement but it is outputting 0 only always. 
 NRF_LOG_INFO("sqrtf(VectorDotProduct(pfJ, pfJ)): %d",sqrtf(VectorDotProduct(pfJ, pfJ))); 
 and no value is showing for the below statement. 
 NRF_LOG_INFO("sqrtf(VectorDotProduct(pfJ, pfJ)): %f",sqrtf(VectorDotProduct(pfJ, pfJ))); 
 
 Thanks.

Hi, 
 Logging float requires you to use the following dedicated macros: 
 
 NRF_LOG_INFO („float value:” NRF_LOG_FLOAT_MARKER „
”, NRF_LOG_FLOAT (val)) 
 
 For more details you may consult the nrf5 documentation regarding logging on Nordic Semiconductors Infocenter. The specific section containing logging float numbers can be found under "Usage -> Logging". 
 
 I hope this helps! Kind regards, Andreas
