Description: Add Analytic Function: Returns the sum of the arguments.
The sum of a real number a and a complex number (x, y) is the complex number (x+a, y).
The sum of two complex numbers (x
1
, y
1
) and (x
2
, y
2
) is the complex number (x
1
+x
2
, y

+y
2
).
The sum of a real array and a complex array is a complex array, where each element x of the real
array is treated as a complex element (x, 0). The arrays must have the same dimensions.
The sum of a binary integer and a real number is a binary integer that is the sum of the two
arguments, truncated to the current wordsize. (The real number is converted to a binary integer
before the addition.)
The sum of two binary integers is truncated to the current binary integer wordsize.
The sum of two unit objects is a unit object with the same dimensions as the second argument.
The units of the two arguments must be consistent.
The sum of two graphics objects is the same as the result of performing a logical OR, except that
the two graphics objects must have the same dimensions.
Common usage is ambiguous about some units of temperature. When ºC or ºF represents a
thermometer reading, then the temperature is a unit with an additive constant: 0 ºC = 273.15 K,
and 0ºF = 459.67ºR. But when ºC or ºF represents a difference in thermometer readings, then the
temperature is a unit with no additive constant: 1 ºC=1 K and 1 ºF =1 ºR.
The calculator assumes that the simple temperature units x_ºC and x_ºF represent thermometer
temperatures when used as arguments to the functions <, >, ≤, ≥, ==, and ≠. This means that, in
order to do the calculation, the calculator will first convert any Celsius temperature to Kelvin and
any Fahrenheit temperature to Rankine. (For other functions or compound temperature units, such
as x_ºC/min, the calculator assumes temperature units represent temperature differences, so there
is no additive constant involved, and hence no conversion.) The arithmetic operators +, –, %CH,
