Hi Eric

Great library. There is a problem with compiling the package on ARM v7 32 bit on this board, which may be related to this issue you opened:

$ uname -a
Linux odroid2 4.14.13-1-ARCH #1 SMP PREEMPT Mon Jan 15 21:22:58 UTC 2018 armv7l GNU/Linux
$ go get github.com/ericlagergren/decimal
# github.com/ericlagergren/decimal
../github.com/ericlagergren/decimal/context.go:12:23: undefined: c.MaxScale

Note that if I cross-compile from a 64-bit linux to target Arm 32bit, it works without issues

Let me know if you need more info.

Cheers,
Silviu

Hmmm. That's fixable, it's just incorrect build tags it seems. Sorry about that, I didn't think of ARM when I set the build constants.

Testing compilation is easy enough (I can do it with GOOS and GOARCH), but I don't have any ARM devices I can test the actual implementation on. (If somebody wants to send me some old Androids or Raspberry Pis I'd be down to make sure the tests pass with flying colors.) I only have two 64-bit machines.

Ran it on a Raspberry Pi. Bunch of tests broke.

Note: this https://github.com/pguyot/arm-runner-action may help (it uses qemu). I'm using it successfully here: https://github.com/spacemeshos/economics/blob/main/.github/workflows/go.yml (works with arm64, but tests fail with 32 bit)
