variable
_
When
variable
has no value, it is treated as
though it represents a complex number. By
default, without the _
, the variable is treated
as real.
If
variable
has a value, the _ is ignored and
variable
retains its original data type.
Note:
You can store a complex number to a
variable without using _
. However, for best
results in calculations such as
cSolve()
and
cZeros()
, the _ is recommended.
Assuming z is undefined:

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
¥ À
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

conversion operator does not handle
temperature units. Use
tmpCnv()
and
@

tmpCnv()
instead.

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.
