Summary of uCalc Fast Math Parser routines:

uCalc	Encapsulates all of uCalc FMP's (and Language Builder's) functionality
ucDefine	Defines an item, such as a function, operator, variable, constant, syntax, pattern, etc.
ucDefineFunction	Defines a function
ucDefineOperator	Defines an operator
ucDefineSyntax	Defines a syntax
ucDefineVariable	Defines a variable
ucError	Returns the error number of the most recent transaction
ucErrorMessage	Returns an error message
ucEval	Evaluates an expression in one step, returning a numeric result
ucEvalStr	Evaluates an expression in one step, returning the result as a string
ucEvaluate	Rapidly evaluates an expression that was already parsed with ucParse
ucEvaluateStr	Same as ucEvaluate, but returns a string
ucGetTrigMode	Returns the current trig mode (Degree, Radian, or Grad)
ucNewThread	Allocates a new thread
ucExprThread	Returns the handle of the thread that has called a callback routine
ucParam	Returns the value (numeric) of a given argument in a callback routine
ucParamCount	Returns the number of arguments that are passed to a callback routine
ucParamHandle	Returns the handle of a given argument in a callback routine
ucParamStr	Returns the value (string) of a given argument in a callback routine
ucParse	Parses an expression; returns a handle for use with ucEvaluate
ucRaiseError	Raises an error by setting the numeric value of the error
ucRaiseErrorMessage	Raises an error by setting a customized error message
ucReleaseItem	Releases an item
ucReturn	Sets the return value (numeric) of a native callback routine
ucReturnStr	Sets the return value (string) of a native callback routine
ucSetTrigMode	Sets the trig mode to Degree, Radian, or Grad

Partial Feature List

• Speedy parsing and evaluations
• Support for .NET, VB, PB, Delphi, VC++, BC++B, and more
• Library of standard arithmetic, trigonometric, relational (comparison), and miscellaneous routines
• 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 DLL 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 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 deleted
• uCalc FMP also inherits a host of other features from the uCalc Language Builder
