/%

Purpose
Returns the quotient of dividing pseudo-probability-numerator by all of the pseudo-probability-denominators, performing pseudo-probability-normalization in the process.

Package   :gbbopen-tools

Module   :gbbopen-tools

Arguments and values

Returns
The pseudo-probability-normalized fixnum quotient (if one or more pseudo-probability-denominators is specified; otherwise the pseudo-probability-normalized fixnum reciprocal of pseudo-probability-numerator.

Description
pseudo-probability-normalization is performed by /%, but the fixnum result may not be a pseudo-probability. It is an error to specify more than one pseudo-probability-denominator value that leads to an intermediate result that is larger than a fixnum.
