What precision does the float type in appfarm have? Is there a way of getting 128 bit precision similar to the decimal type in C#?
The “float” type in Appfarm uses 64-bit precision (IEEE 754 double) and does not provide 128-bit precision like C#'s decimal type.
128-bit precision decimal is supported in MongoDB, but not in Javascript. There has been a proposal to include this data type in JS (read more here). We are monitoring the progress of this proposal, but are not expecting it to be included shortly.
However, we would like to hear about your use case requiring 128-bit precision to inform future prioritization processes.
We are building an app for calculating profitability of projects based on capital expenditure, operational costs, economical assumptions, and expected revenue. I think 64-bit precision will be acceptable in our case.
