Basic Examples  (2)

Indeterminate is returned when a value cannot be unambiguously defined:

Any numeric function of Indeterminate also gives Indeterminate:

Scope  (3)

Indeterminate "takes over" any function with attribute NumericFunction:

Negative precision/accuracy can yield Indeterminate:

Infinity in an unknown direction:

Generalizations & Extensions  (1)

Mathematical operations with Indeterminate produce Indeterminate:

Indeterminate threads over lists:

Applications  (1)

Digits beyond the limit of precision are Indeterminate:

Create a number of lower precision:

Properties & Relations  (1)

Indeterminate is not a number:

It is neither real nor complex:

Possible Issues  (5)

The value cannot be unambiguously defined:

Use Limit to resolve the value:

The answer is valid for generic parameter values:

This particular parameter value gives an Indeterminate result:

Use Limit to resolve the value:

Each iteration will result in lower precision:

In this case an equivalent function does not lower precision:

Sometimes a higher precision is needed:

Indeterminate does not equal itself:

Use SameQ for testing against Indeterminate:

Indeterminate in functions with special evaluation semantics might go undetected:
