Converting Between Strings and Floating-Point Numbers

Once you have created a NumFormatStringRec record that specifies how numbers are represented, as described in "Using Number Format Specification Strings for International Number Formatting," which begins on page 5-94, you can use two other Text Utilities routines to convert between string and floating-point representations of numbers. Floating-point numbers are stored in standard Apple (SANE) format.

• The StringToExtended function converts the string representation of a number into a floating-point number, using a NumFormatStringRec record to specify how the input number string is formatted.
• The ExtendedToString function converts a floating-point number into a string that can be presented to the user, using a NumFormatStringRec record to specify how the output number string is formatted.
