Hello,

When building the demo with GCC, ensure that the demo and platform library are built with this option:

<code> <br>CHOOSE_FLOAT=HARD_FP <br> </code> Otherwise, the project does not use the Kinetis device’s hardware floating point when using the CMSIS-- DSP library.

In addition please check the below threads.

printf() with float values

GENERAL: PRECISION OF PRINTF %F FORMAT STRING

Have a great day,
Sol
