Function den #

Get the denominator of a fraction. For a fraction a/b, the function returns b.

The result is always in lowest terms. For example, den(fraction(8, 6)) returns 3n because 8/6 simplifies to 4/3.

For negative fractions like -a/b or a/-b, the denominator is always returned as a positive bigint. The sign is stored in the numerator. So den(fraction(-2, 3)) and den(fraction(2, -3)) both return 3n.

For matrices, the function is evaluated element wise.
