Numerical Calculations (Mathematica Tutorial)

Exact symbolic results are usually very desirable when they can be found. In many calculations, however, it is not possible to get symbolic results. In such cases, you must ...

RuntimeOptions (Built-in Mathematica Symbol)

RuntimeOptions is an option for Compile that specifies runtime settings for the compiled function it creates.

ConditionalExpression (Built-in Mathematica Symbol)

ConditionalExpression[expr, cond] is a symbolic construct that represents the expression expr when the condition cond is True.

InitializationGroup (Built-in Mathematica Symbol)

InitializationGroup is an option for the first cell of a cell group that specifies whether the group should be tagged to be evaluated by the Mathematica kernel when the ...

While (Built-in Mathematica Symbol)

While[test, body] evaluates test, then body, repetitively, until test first fails to give True.

TimeConstraint (Built-in Mathematica Symbol)

TimeConstraint is an option for various algorithmic functions which specifies how long to spend trying a particular transformation or part of an algorithm.

Compile (Built-in Mathematica Symbol)

Compile[{x_1, x_2, ...}, expr] creates a compiled function that evaluates expr assuming numerical values of the x_i. Compile[{{x_1, t_1}, ...}, expr] assumes that x_i is of a ...

WorkingPrecision (Built-in Mathematica Symbol)

WorkingPrecision is an option for various numerical operations that specifies how many digits of precision should be maintained in internal computations.

Low-Level System Spelunking (Mathematica Guide)

Mathematica is a large and complex software system. Although strongly not supported for production purposes, it is sometimes instructive to "spelunk" in the system, looking ...

$Pre (Built-in Mathematica Symbol)

$Pre is a global variable whose value, if set, is applied to every input expression.
