@gaetbout There's an issue with the code in the macros package with the new Cairo version. The pow! macro isn't working. To be honest I think that this macro can be removed as they added pow to the corelib.
@0xLucqs FYI

[gaetbout]

I think, this was more to showcase how to make your own macro.
@milancermak, can you help here?

[0xLucqs]

I’ll push the fix tomorrow

[milancermak]

I think it's still worth keeping it. The macro calculates the result at compile time (i.e. it's a constant), it's nice to have sth like pow!(10, 18) instead of 1000000000000000000 for readability, esp. in defi apps.
