How to obtain a absolute of a number in Xilinx Simulink?

Question

I need to get the absolute of the signal in Xilinx Simulink.

I can use a mcode block and write matlab code to achieve it. But, just curious if there is a better way of doing it.

I am very new to using Simulink(Xilinx). Is there any abs block as in Simulink in Xilinx library.

Thanks
