## (Power)

Type:
Function
Description: Power Analytic Function: Returns the value of the level 2 object raised to the power of the level
1 object. This can also apply to a square matrix raised to a whole-number power.
If either argument is complex, the result is complex.

### (Where)

Type:
Function
Description: Where Function: Substitutes values for names in an expression.
| is used primarily in algebraic objects, where its syntax is:
' symb
| (name
old
It enables algebraics to include variable-like substitution information about names. Symbolic
functions that delay name evaluation (such as ∫ and ) can then extract substitution information
from local variables and include that information in the expression, avoiding the problem that
would occur if the local variables no longer existed when the local names were finally evaluated.
