ProCalc is a powerful programmable scientific calculator that incorporates a highly capable BASIC interpreter together with six programmable keys (P1-P6) allowing six programs to be loaded at any time.

ProCalc 2+ also comes with a built in spreadsheet that can be used in the traditional manor as well as being programatically accessible from the built in programming language.

ProCalc 2 is released as DonationWare. It is unrestricted and doesn't use any annoying adverts to fund its development. If you find the application useful then please consider making a donation to reflect what it is worth to you or your organisation.

FEATURES

• BASIC Interpreter with 10 data types (Boolean, Byte, Complex, Double, Float, Integer, Long, Short, String and Variant) and wide range of functions including:- calculator memory access, reading and writing files, 51 maths functions, 11 string functions, 12 date and time functions, 29 graphics functions, 3 graph drawing functions, 3 touch screen functions and a couple of functions for generating messages and prompting for data input.

• Works in Decimal, Binary, Octal, Hexadecimal and Statistical modes.

• Degrees, Radians, Gradians and Hyperbolic Trigonometry modes.

• Fix, Sci, Eng, Fractional and Normal display formats for controlling the number of decimal points / significant figures etc.

• Standard Trigonometric Functions including:- Sine, Cosine, Tangents, Secant, Cosecant, Cotangents and their inverse functions.

• Hyperbolic Trigonometric Functions including:- Sine, Cosine, Tangents, Secanant, Cosecant, Cotangents and their inverse functions.

• Ten Memory including MS, M+, M-, MR.

• Percentage function

• Common Logarithm (Base 10), Binary Logarithm (Base 2) and Natural Logarithm (Base e)

• X^2 and Square Root

• X^n and X root n

• Reciprocal (1/x)

• Factorial using the gamma functions allows the factorial of non-integer numbers.

• Built in constants including:- pi, e, g and c.

• Binary operators include AND, OR, XOR, NOT, NAND, NOR, XNOR, RoL, RoR, AsL, AsR, LsR, RoLC, RoRC and BitX (Special function for extracting and combining arbitrary bits from a word: FEDC bitx F0F0 outputs 00FD).

• Binary, Octal and Hexadecimal modes can be used with either 8 bit, 16 bit, 32 bit or 64bit word size.

• Statistical Mode allows the calculation of Sum of values, sum of squares, mean (x-bar), population standard deviation, sample standard deviation and variance.

The programmable calculator comes with an extensive help system and several examples programs. The pre-written programs include:-

System Programs

• System/Area - Calculate area of circles, cones, cubes, ellipses, rectangles, spheres, squares and triangles.

• System/Convert:- Converts between various distances, areas, volumes, masses and speeds.

• System/Volume - Calculate volume of boxes, cones, cubes, cylinders, pyramids and spheres.

Example Programs

• Examples/Constants - Template Program for making a list of Constants.

• Examples/Demo - Demo showing how graphics can be used within ProCalc

• Examples/FileIO - FileWrite option writes current calculator value into a file. FileRead option reads a value from a file and sets it as the calculators value,

• Examples/Graphs - Draws Cosine, Sine and Tangent Graphs.

• Examples/Hello - The Hello World Program!
