Function num #

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

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

For negative fractions like -a/b or a/-b, the sign is always included in the numerator. Both forms are normalized internally, so num(fraction(-2, 3)) and num(fraction(2, -3)) both return -2.

For matrices, the function is evaluated element wise.
