local function fraction_table(parms, value, denominator)

-- Return value as a string or a table:

-- * If result is a string, there is no fraction, and the result

Line 1,566:

-- * If result is a table, it represents a fraction with named fields:

-- wholestr, numstr, denstr (strings of en digits for integer, numerator, denominator).

-- The result is rounded to the nearest multiple of (1/denominator).

-- The result is rounded to the nearest multiple of (1/denominator), or

-- optionally is rounded down.

-- If the multiple is zero, no fraction is included.

-- No fraction is included if value is very large as the fraction would
