$IterationLimit::itlim

Details

  • This message is generated when the number of iterative evaluations of an expression exceeds the indicated limit.
  • The limit on the number of iterative evaluations of an expression is determined by the value of $IterationLimit.
  • If your calculation requires a large number of iterative evaluations, you can set the value of $IterationLimit to a large positive integer or to Infinity.
  • This message is sometimes caused by syntax errors, such as misplaced "=" signs.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[$IterationLimit::itlim].

Examples

Basic Examples  (1)

With this rule for f[p_], evaluation of f[p-1] will lead to infinite iteration:

Wolfram Language code: f[p_] = f[p - 1]

Clear the rule for f[p_]:

Wolfram Language code: Clear[f]

A termination rule can be added so that the iteration will stop:

Wolfram Language code: f[p_Integer] = f[p - 1]
Wolfram Language code: f[0] = 1
Wolfram Language code: f[10]

Clear the rules for f:
