Controlling the Precision of Results (Mathematica Tutorial)

In doing numerical operations like NDSolve and NMinimize, Mathematica by default uses machine numbers. But by setting the option WorkingPrecision->n you can tell it to use ...

$RecursionLimit (Built-in Mathematica Symbol)

$RecursionLimit gives the current limit on the number of levels of recursion that Mathematica can use.

Sum (Built-in Mathematica Symbol)

Sum[f, {i, i_max}] evaluates the sum \[Sum]i = 1 i_max f. Sum[f, {i, i_min, i_max}] starts with i = i_min. Sum[f, {i, i_min, i_max, di}] uses steps d i. Sum[f, {i, {i_1, i_2, ...

AlgebraicNumberNorm (Built-in Mathematica Symbol)

AlgebraicNumberNorm[a] gives the norm of the algebraic number a.

MatchingDissimilarity (Built-in Mathematica Symbol)

MatchingDissimilarity[u, v] gives the matching dissimilarity between Boolean vectors u and v.

$MessageList (Built-in Mathematica Symbol)

$MessageList is a global variable that gives a list of the names of messages generated during the evaluation of the current input line.

BitOr (Built-in Mathematica Symbol)

BitOr[n_1, n_2, ...] gives the bitwise OR of the integers n_i.

BooleanVariables (Built-in Mathematica Symbol)

BooleanVariables[expr] gives a list of the Boolean variables in the Boolean expression expr.BooleanVariables[bf] gives the number of Boolean variables in the BooleanFunction ...

Not (Built-in Mathematica Symbol)

! expr is the logical NOT function. It gives False if expr is True, and True if it is False.

NumberFieldDiscriminant (Built-in Mathematica Symbol)

NumberFieldDiscriminant[a] gives the discriminant of the field \[DoubleStruckCapitalQ][a] generated by the algebraic number a.
