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.

Type: Function
Description: Subtract Analytic Function: Returns the difference of the arguments.
The difference of a real number a and a complex number (x, y) is (x–a, y) or (a–x, –y). The
difference of two complex numbers (x
1
, y
1
) and (x
2
, y
2
) is (x
1
– x
2
, y
1
– y
2
).
The difference 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 two array arguments must have the same
dimensions.
The difference of a binary integer and a real number is a binary integer that is the sum of the first
argument and the two’s complement of the second argument. (The real number is converted to a
binary integer before the subtraction.)
