Compiles OK for me - what version of Flowcode are you using - and what errors are you getting?

Version I use is Flowcode AVR V5.3.0
Error code is here,
"Main.c:(.text+0x2bc): undefined reference to `float32_sqrt'

Error returned from [avr-gcc.exe]
Return code = 1
Flowcode was unable to compile the flowchart's C code due to the following errors:


If your flowchart contains C code, please review this carefully. If your flowchart contains no C-code or you have thoroughly reviewed the code, contact Technical Support."

- that's a job for Matrix's boffins....

I can offer a sqrt macro that will do the job in the meantime:

The demo (main) code just displays the sqrt of 100 randomish numbers...
