If complex mode is set (flag -103 set), FROOTS looks
for complex solutions as well as real solutions.
If approximate mode is set (flag -105 set) FROOTS
searches for niuneric roots.

FXND
Type:
Command
Description:
Splits an object iirto a numerator and a denominator.
Access:
Catalog, (C@
Input:
A fraction, or an object that evaluates to a fraction.
Output:
The object split into numerator and denominator.
Level 2/Item 1: The niunerator.
Level 1/Item 2: The denominator.
Flags:
