ParseNumber


ParseNumber(x, badVal, decimal)

It converts text «x» to a numeric value, if it has a number format (including dates or time) that is valid in Analytica. If not, e.g. ParseNumber("hello"), it returns Null, or «badVal» if specified. If «x» is already a number, it just returns the value «x».

If «x» uses a comma for the decimal point, such as "3.14", specify the «decimal» parameter to be ','. («decimal» requires Analytica 5.0)

Library

Text Functions

Example

ParseNumber('3.14') → 3.14
ParseNumber( x, x )      { Keeps cells that don't parse as text }
ParseNumber('3,14', decimal:',') → 3.14

Notes

If «x» is an array, it will try to parse each element of the array -- it fully supports Intelligent Arrays, like most Analytica functions.

ParseNumber is often useful when reading data from flat files, using ReadCsvFile or ReadTextFile. [[ParseCSV] tries to parse numbers automatically (by default), so you don't need to use ParseNumber.

You can coerce a text to be numeric in other ways. For example, you can declare a function parameter with the qualifiers "Coerce Numeric". If the actual parameter is text, it will try to convert it to a number when it calls the function. The Number format of the variable that contains the call to the function determines how the value is interpreted. Usually, it should not be a date number format.
