https://devzone.nordicsemi.com/f/nordic-q-a/87354/sprintf-with-sdk-17-1I&#39;m trying to get sprintf working with SDK 17.1. Basically, I&#39;m struggling getting this simply use-case to work. char buf[32]; sprintf(buf, &quot;%.3f&quot;, 3,5); I&#39;m not able to find a flag that enables this support. Any assistant would be greatly appreciateden-USTelligent Community 13Wed, 27 Apr 2022 12:44:22 GMThttps://devzone.nordicsemi.com/thread/365197?ContentTypeID=1Wed, 27 Apr 2022 12:44:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2a1eaf6b-5c94-4246-ac14-980a9d11a980J&#248;rgen Holmefjord<p>Hi,</p> <p>Which compiler/IDE are you using?</p> <p>In Segger Embedded Studio, there is a project option to enable float support for printf:</p> <p><img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/ses_5F00_printf_5F00_float.png" /></p> <p>You also likely need to change your &quot;float&quot; from &quot;3,5&quot; to &quot;3.5&quot;, comma is used to separate different parameters.</p> <p>I verified that the float in sprintf works in UART peripheral example in SES, with the above option set to &quot;float&quot;.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
