"Real" (Interpreter Type)

Real number in a standard format.

Details

  • "Real" can be used in Interpreter and related constructs, including deployed smart form fields.
  • Use of "Real" does not require connectivity to the Wolfram Cloud.

Allowed Forms

  • 1234integers
    -1234negative integers
    12.34real numbers
    12.45e45numbers in scientific notation
    1.2E-5numbers in scientific notation
    1.2345`2numbers with a given Precision
    1.2345``4numbers with a given Accuracy
    12,456integers with separators
    12,345.67real numbers with separators

Examples

Basic Examples  (3)

Interpret real numbers:

Wolfram Language code: Interpreter["Real"]["3.2e5"]
Wolfram Language code: Interpreter["Real"]["-2."]

Restrict in a range:

Wolfram Language code: Interpreter[Restricted["Real", {0, Pi}]][{"3.14", "3.15"}]

Set the precision:

Wolfram Language code: Interpreter[Restricted["Real", Automatic, 3]]["3.1415926535897932384"]

Otherwise, $MachinePrecision is implied:

Wolfram Language code: Interpreter["Real"]["3.1415926535897932384"]

Use a different number point and/or block separator:

Wolfram Language code: Interpreter["Real", NumberPoint -> ",", NumberSeparator -> "."]["1.002,34"]

Set the precision:

Wolfram Language code: Interpreter[Restricted["Real", Automatic, 3]]["1.09276"]

Otherwise, $MachinePrecision is implied:

Wolfram Language code: Interpreter["Real"]["1.09276"]//Precision

When the number contains a Precision or Accuracy, and a precision restriction is also specified, the lower of the two will be applied:

Wolfram Language code: Interpreter[Restricted["Real", Automatic, 10]]["1.23456789`3"]
Wolfram Language code: Interpreter[Restricted["Real", Automatic, 2]]["1.23456789``10"]
