How to include math library?

Honored Contributor II

Hello guys  

I am new to FPGA, these days I'm trying to use NIOS II to do some digital current stuff, SO I need complex functions stuff. 


And I found a "Libquadmath " documentation in the "nios2eds" folder which has something like complex data type and related complex functions, 


However, I didn't found something like quadmath.h ... 


Do you guys know where is this "libquadmath" library located at? 


also how to include the library into the nios-ii eclipse?  


I have successfully run some basic LED manipulations here, but still, i don't understand how this works  


I try to read the nios- ii handbooks but I found myself too stupid to understand. 


Thanks a lot!:eek:
