I wonder if we should ask the gojq author what he thinks of decimal support. He has already extended from original jq to support arbitrarily precision so maybe he has some ideas. Would be nice to not have too much difference compared to upstream.
btw any idea if big.Rat
from standard library would be ok also?

Good idea, I opened an issue on gojq
requesting support for arbitrary precision non-integer decimal values: itchyny/gojq#216
I believe big.Rat
can represent all numbers that shopspring/decimal
can represent and seems to support the required arithmetic operations (except modulus, which would probably be accomplished by truncating the big.Rat
to a big.Int
and using that to calculate modulus). The main difficulty with big.Rat
in the context of fq
is that to get a decimal-with-radix representation (i.e. "123.4" instead of "1234/10") you use FloatString, which requires you to specify (and keep track of) the required number of digits of precision yourself. It's worth an experiment to validate if it's possible.
