expression_unit1 4 _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 chapter about constants and
measurement units in this book. You can
press:
TI-89: 2 9
TI-92 Plus: ¥À to select units from a
menu, or you can type the unit names
directly.
To get the _ underscore when typing units
directly, press:
TI-89: ¥
TI-92 Plus: 2
Note: The 4 conversion operator does not
handle temperature units. Use tmpCnv() and
@tmpCnv() instead.

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.
