RPN Scientific+ is a scientific, programmer, and statistics
calculator using Reverse Polish Notation. It allows entry in
and simultaneously displays values in decimal, hexadecimal,
binary, and time notation. The programmer functions allow
displaying values of Long, Short, and Byte signed or unsigned
numbers. Numbers and basic functions can be entered using the
number pad on your keyboard.
The calculator is stackbased with 4 registers. The stack can
be manipulated using the buttons in the upper right of the
calculator. They function per Forth language counterparts.
Various options can be set by toggling the green keys. For
example, DEG when pressed toggles from angles in degrees to
angles in radians. The FP button alternates between floating
point and integer mode. Entering in the Hex or Binary
display triggers integer mode. Press FP to return to floating
point.
Purple keys have alternate functions that can be accessed via
the purple Alt button. The alternate functions are closely
related to the normal functions. For example, the alternate
function for the SIN button is ArcSine.
/MOD returns the quotient (x reg) and remainder (y reg) from
dividing the y register by the x register using modulo division.
MOD returns only the remainder of the division in the x register.
PUT 09 stores the x register in register 09.
GET 09 recalls the stored value back to the x register.
SIGN toggles between signed and unsigned bit interpretations.
SUM+ accumulates statistics for the values in x and y registers.
SUM can be used to remove data due to an entry mistake.
MEAN displays xbar in x, ybar in y, sx in z, sy in t register.
L.R. displays the regression intercept in x, slope in y, and
correlation coefficient (r) in the z register.
The above statistics are accumulated as follows. Use GET to
view the desired register.
n in register 2 (also shown during accumulation in x
register)
SumX in register 3
SumX^2 in register 4
SumY in register 5
SumY^2 in register 6
SumXY in register 7
