Printing a float value

[Vijayneerukanti]

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 „\r\n”, 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
