[r6rs-discuss] Confusion over |p

The description of number->string in section 11.7.4.4 says:

"If a precision is specified, then the representations of the inexact
real components of the result, unless they are infinite or NaN, specify
an explicit <mantissa width> p, and p is the least p ? precision for
which the above expression [read-write invariance] is true."

Once we agree (!) what |p means, can someone point me to an algorithm to
calculate "the least p ? precision" for which read-write invariance is true?

Regards,

Alan
