Predefined Functions - part_k
| Function name: | part_k - Return the 'k' component of the argument |
| Synopsis: | part_k(q) |
| Input data type | Output data type |
|---|---|
| real | real |
| complex | real |
| quaternion | real |
Description:
Returns the k component of a real, complex or quaternion number. The result is always a real number. If the argument is a real or complex number, it always returns 0. Thus the function only makes sense with quaternion numbers (r,i,j,k). There it returns the fourth component.
