Math libraries in C for AM335X processors ?

Hi,

Are there any libraries for doing simple math functions in C like sin(x), cos(x) on the Beaglebone's AM335X processor ?

I found this http://www.ti.com/tool/MATHLIB library. But they seem to be only for C6XXX processors.

Thanks !

Hi,

math.h works great

I am looking at the math.h file in the following directory and do not see any implementation of sin(), etc:

/ti-sdk-am335x-evm-06.00.00.00/linux-devkit/sysroots/armv7ahf-vfp-neon-3.2-oe-linux-gnueabi/usr/include

Could you be more specific as where these trig functions are located?

Thanks,

Paul

I solved my issue by using <tgmath.h> and then using the -lm linker command line argument. I believe this instructions the linker to use legacy libs (someone correct me if I am wrong).
