Calculate
function
The result is shown next:
In RPN mode, recall that argument
y
is located in the second level of the stack,
while argument
x
is located in the first level of the stack. This means, you
should enter
x
first, and then,
y
, just as in ALG mode. Thus, the calculation of
%T(15,45)
, in RPN mode, and with system flag 117 set to
CHOOSE boxes
,
we proceed as follows:

Enter first argument

Note:
The exercises in this section illustrate the general use of calculator
functions having 2 arguments. The operation of functions having 3 or more
arguments can be generalized from these examples.
As an exercise for percentage-related functions, verify the following values:
%(5,20) = 1, %CH(22,25) = 13.6363.., %T(500,20) = 4
Minimum and maximum
Use these functions to determine the minimum or maximum value of two
arguments.
MIN(x,y) : minimum value of x and y
MAX(x,y) : maximum value of x and y
As an exercise, verify that
MIN(-2,2) = -2, MAX(-2,2) = 2
Modulo
MOD: y mod x = residual of y/x, i.e., if x and y are integer numbers, y/x =
d + r/x, where d = quotient, r = residual. In this case, r = y mod x.
