HP 48gII Graphing, 50g Graphing –(Subtract)

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.

–(Subtract)

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 (x1, y1) and (x2, y2) is (x1 – x2, y1 – y2).

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.)
