+% 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.
