Global Computation Settings & Parameters
The Wolfram Language is built to handle arbitrarily large computations—limited only by computer time and memory—and provides a collection of convenient global safety features to prevent programs from going out of control.
Limiting Computations
$RecursionLimit — maximum recursion depth
$IterationLimit — maximum number of iterations
$MaxPiecewiseCases ▪ $MaxRootDegree
TimeConstrained ▪ MemoryConstrained ▪ TimeConstraint
Numerics
$MaxExtraPrecision ▪ $MinPrecision ▪ $MaxPrecision ▪ $NumberMarks
Computational Parameters
$Assumptions — global assumptions to make about variables, etc.
