awful: function: pow

Declaration

mixed :pow ( mixed &ARG , … )
mixed :^ ( mixed &ARG , … )

Summary

Takes any number of arguments. Performs power between the rightmost pair of elements, then the second-rightmost, et cetera. Lifts the value of the left element to the power of the value of right one. Note that references will modify the values of variables.
Returns a copy of the value the leftmost argument ended up with.

Power rules

The table below contains rules for powering values. Note that these rules are non-symmetrical; swapping the values may yield a different result. The row contains the type of the first (left) value in pair, while the column contains the type of the second (right) value in pair.

	NIL	bool	bin	float	string	array
NIL	Arithmetics on NIL values have no effect.
bool	No effect.
bin	Number is set to 1.	If bool is FALSE, number is set to 1.	No type juggling needed.	Power is calculated, result truncated and put into integer.	String is converted to number (with regard to base).	Powers by the number of entries in structure.
oct
int
hex
float	Float is set to 1.0.	If bool is FALSE, float is set to 1.0.	No type juggling needed.		String is converted to float.	Powers by number of entries in structure.
string	No effect.
array	Powering is performed on each structure element separately.					Powering is performed between keys present in both structures.
dict	Powering is performed on each structure element separately.

Example

# :pow example.
:set &D :sysinfo-disk-total
:mkfloat &D
:div &D :pow i2 i30
:writeln s'Disk size: ' $D s'GiB'
