uCalc Developer Subscription
This entitles you to a license for uCalc Language Builder (Standard), uCalc Fast Math Parser (Standard), uCalc Graphing Calculator, Dacorbi Pattern Search, and all upgrades for these or any new uCalc product with a price tag of less than $1,000 released within the annual subscription period. The yearly subscription is not renewed automatically. The following year you may either re-subscribe, or if you no longer need any upgrades you may keep the product versions you already have.

uCalc Graphing Calculator
If you are a student who wants to plot those equations the teacher gave for math assignment, or an engineer looking for a great scientific calculator, or a home user who wants to convert between units of measure (such as teaspoons to tablespoons for that special recipe), or you want to compute the number of mortgage payments that are left by simply filling in the blanks, then this multi-purpose calculator is for you.

uCalc Graphing Calculator Features:

• Interactive Animated Tutorial - Sit back and watch (and interact) as an animated character walks you through many of the calculator's features. You may likewise create your own tutorials to demonstrate math lessons by programming the animated character.
• Expression Evaluator - It comes with many built-in functions, operators, numeric bases, numeric formats, and modes.
• Unit Converter - You can convert between units of measure in a flexible manner. You'll find categories such as Length, Capacity, Weight, Temperature, Time, and more.  You can even add your own categories and units.
• User Solution Modules - You can interactively define and solve problems by simply filling in the blanks, without directly having to manipulate math formulas. To get you started, uCalc comes with useful financial modules that will let you calculate things like add-on interest, compound interest, ordinary annuity sum, present value (mortgage), and more.  You might find yourself eventually creating your own modules to solve all kinds of other problems with this unique feature.
• Graphing- You can plot Cartesian, polar, parametric, 3D equations, or coordinates from data files.  You can print your graphs, or save them for later use.
• Equation Solver - You can solve for the unknown value in an equation.  If your equation has several solutions, this calculator can display them all.  If there are several solutions, but you are interested in only the negative ones for instance, you can enter the solution range you want uCalc to work in.
• User Functions and Variables - You can define variables with meaningful names, and functions with multiple parameters for use anywhere in the program.
• Summation Tables - You can use this general mathematical tool for practical things such as calculating annuity, compound growth, etc...
• Integrator- You can do numerical integrations as well.
• Saving/Loading - You can save your work, and load it later, or paste it to the clipboard in various convenient ways.
• Adder - If you want to add up a bunch of numbers, such as prices alongside the product descriptions in your shopping list, you can do this conveniently with the Adder.

uCalc Language Builder (beta)
The uCalc Language Builder takes parsing to the next level. In addition to math expressions, it can also parse source code.

It lets you define the language for it to parse. BASIC, Forth… or your own new language, it's up to you. uCalc removes the complexity and mystery normally associated with language building. You can even define your language interactively with the provided interpreter.

uCalc Fast Math Parser
uCalc Fast Math Parser allows programs to evaluate math expressions that are defined at run time. Ease of implementation, flexibility, sturdiness and speed are at the core of the product's design.  It includes direct support for Borland C++ Builder, Delphi, PowerBASIC (PB/DLL and PB/CC), Visual Basic (classic), .NET (C#, VB.NET etc), and Visual C++.

uCalc Fast Math Parser Features:

• Speedy parsing and evaluations
• Support for .NET, VB, PB, Delphi, VC++, BCB++, and more
• Library of standard arithmetic, trigonometric, relational (comparison), and miscellaneous routines (for both numbers and strings).
• User-defined operators and functions, with support for overloading, overshadowing, bootstrapping, or recursion; optional arguments, fixed or indefinite number of arguments; multi-statements separated by semicolons
• Function/operator definitions can either be self contained, or attached to routines from your host program or any conventional DLLs such as the Windows API or other
• User operator definitions can be infix, prefix, or postfix, and can be given a precedence level; an operator can be alphanumeric or be composed of symbols
• User-defined variables (and constants) can be internal, or attached to a variable in your host program, or any valid memory address
• A user variable can be defined as a temporary local item
• Selected definitions can be locked to prevent redefinition
• Supported data types include: Byte, Integer, Long, Dword, Single, Double, Extended, Currency, SortedList, Table, LPCSTR (null-terminated string), FixedLength string, dynamic String, user-defined types, and more
• Multi-threading
• FPU control
• Exception handling (for overflow, division by zero, etc.) and general error handling
• User-defined character patterns and syntax constructs
• Items (functions, variables, operators, ...) can be renamed, or undefined
• uCalc FMP also inherits a host of other features from the uCalc Language Builder

Dacorbi Pattern Search
Dacorbi Pattern Search allows you to perform search and search/replace operations on text using easy-to-understand but powerful patterns. No need to understand complicated regular expressions. Any non-programmer who can understand how to do a search using Windows Notepad or Microsoft Word can quickly understand how to use this program in a powerful way. And if you are a programmer, this product supports advanced techniques that will let you perform search/replace operations that previously would have seemed either impossible or too complex.
