All of us fintech devs however, know the true horrors. Make everything a string, lest ye end up in precision hell
You are a fintech dev using floating point? And your advice is to encode things as strings?
...
This is why I got out of fintech.
(I am sorry, I know there are horrors and I am sure I am not familiar with your exact scenario.)
Edit: just for anyone who passes by: try to stick with integers in a currency's smallest unit of division. (This is only one small bit of this problem, but the number of times I have seen currency values in floating point makea me psychotic.)
And then the marketing department comes up with products that cost 1.5ct apiece.
Oh yeah, and some things like petrol are calculated to fractions of a cent as well
