+%  Method FormatMagickStringNumeric formats output for a single numeric
+%  argument. It takes into account that the format string given might be
+%  untrusted user input, and returns the length of the formatted string.
+%
+%  The format of the FormatMagickStringNumeric method is:
+%
+%      long FormatMagickStringNumeric(char *string,const size_t length,
+%                                     const char *format,int value)
+%
+%  A description of each parameter follows.
+%
+%   o string:  FormatMagickStringNumeric() returns the formatted string in this
+%     character buffer.
+%
+%   o length: The maximum length of the string.
+%
+%   o  format:  A string describing the format to use to write the numeric
+%      argument. Only the first numeric format identifier is replaced.
+%
+%   o  value:  Numeric value to substitute into format string.
