Short: RPN scientific and programmer calculator Author: Nathan Hesterman Uploader: riversidepapa zoho com (Nathan Hesterman) Type: misc/math Version: 1.02 Replaces: misc/math/RPNScientific.lha Architecture: i386-aros; m68k-amigaos>=3.0 Distribution: Aminet 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 stack-based 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 0-9 stores the x register in register 0-9. GET 0-9 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 RPNScientific+ was written with Hollywood 8 and Annotate.
