Variable.Format(String) Method

Description

Converts the number held by the calling Variable into a string based on the format specifiers given by formatString. The format specifiers are standard C/C++ specifiers as used with the sprintf function. The Format method converts a double precision floating point value to a string; the IFormat method should be used to convert an integer value to a string.

The format is specified using the syntax shown below. Each field is a single character or a number signifying a particular format option. The flag(s), width, precision, and length are optional. The simplest format specifications contain only the percent sign and a type character (for example, "%f"). A common format specification is rounding a floating point to a number of digits after the decimal point. For more information, see the Parsing Arbitrary String Data reference.
