Description

It'd be nice if we could specify the number of digits of precision so simulated file outputs didn't get so huge. As is, I see things like this:

K <- 4
N <- 32
x <- 
structure(c(1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1,
1, 1, 1, 1, 1, 1, 1, 1, 1, 0.0436764488507174, -0.310472063173452,
1.74928640167937, -1.52005793042295, -0.718757839520306, 0.233486781358933,

Research direction

Locate and read the stan_rdump entry point, then inspect how it formats numeric values for simulated files. Determine where a precision setting belongs and verify that the resulting output uses the requested maximum digits while preserving the existing file structure.
