Calculating absolute value of floating point variable on CLA-C

Lucas Sinopoli

Hello Everyone,

I need to calculate the absolute value of a variable on the CLA under C code. Using assembly is as simple as using MABSF32, but with CLA-C I cannot write that. I'm using a 28035.

Do you have any idea on how to solve it?

Thanks,

Lucas

Hi Lucas,

The intrinsic 'fabs()' is supported by the CLA-C compiler and will give you the floating point absolute.
