4444 (convert) 2  key
expression_unit1 4444 _ unit2 ⇒ ⇒ ⇒ ⇒ expression_unit2
Converts an expression from one unit to another.
The units must be in the same category.
The _ underscore character designates the units.
For a list of valid pre-defined units, refer to the
module about constants and measurement units.
You can press 2
9 to select units from a
menu, or you can type the unit names directly.
To get the _ underscore when typing units
directly, press ¥ 
Note: The
4 conversion operator does not handle
temperature units. Use tmpCnv() and
@ @ @ @tmpCnv() instead.

Returns 10 raised to the power of the argument.
For a list, returns 10 raised to the power of the
elements in
list1 .

10^( squareMatrix1 )
⇒ ⇒ ⇒ ⇒ squareMatrix
Returns 10 raised to the power of squareMatrix1 .
This is not the same as calculating 10 raised to
the power of each element. For information about
the calculation method, refer to
cos() .
squareMatrix1 must be diagonalizable. The result
always contains floating-point numbers.
