3-300 Full Command and Function Reference
The difference of two binary integers is a binary integer that is the sum of the first argument and
the two’s complement of the second argument.
The difference 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.
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 0 ºF = 459.67 ºR. 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, and %T treat temperatures as differences, without any
additive constant, but require both arguments to be either absolute (K and ºR), both ºC, or both
ºF. No other combinations are allowed.
