Details

  • This message is generated when the value of the ExponentFunction option does not give the expected result.
  • When formatting an inexact number, the value of the ExponentFunction option is applied to the exponent that would be used to format the number in scientific notation.
  • The value of the ExponentFunction option should be a function that takes an integer argument and returns an integer or Null. A return value of Null causes no exponent to be displayed. The pure function Null& applied to any argument will return Null.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[AccountingForm::expint].

Examples

Basic Examples  (1)

This input generates a warning message because Null[n] evaluates to itself:

Wolfram Language code: NumberForm[0.000000001234, ExponentFunction -> Null]

This shows a correct use of the ExponentFunction option:

Wolfram Language code: NumberForm[0.000000001234, ExponentFunction -> (Null &)]
