ScanDecimal

Unit:SDL_math1
Class:none
Declaration:function ScanDecimal (Instring: string; var Idx: integer): longint;

The function ScanDecimal decodes a decimal number from a string. The parameter Instring contains the decimal number to be scanned, starting at the position defined by the parameter Idx. Valid characters are the digits ‘0’...’9’, leading ‘-‘ and ‘+’ signs, and leading blanks.

On return, ScanDecimal contains the corresponding integer number, and the variable parameter Idx points to the first character after the scanned number. If the decimal number constitutes the final part of the string, Idx points to 1+length(Instring ).
