Standard functions

Working with numbers

function Abs(e : Extended) : Extended;
Returns absolute meaning of argument e (e by modulus)
Working with strings

function StrGet(var S : String; I : Integer) : Char;
Returns element of string S with index I.

procedure StrSet(c : Char; I : Integer; var s : String);
Sets element of string S with index I in meaning c.

function Uppercase(s : string) : string;
Returns string s in upper case.
function Lowercase(s : string) : string;
Returns string s in lower case.
function Trim(s : string) : string;
Returns changed string s: all beginning and ending “spaces” and control symbols are deleted.
function Length(s : String) : Longint;
Returns length of string s.

procedure SetLength(var S: String; L: Longint);
Sets length of string S in L.

function inttostr(i: Longint): string;
Returns string, that contains transformed integer value i.

function strtoint(s: string): Longint;
Returns integer value, taken from string s.

function strtointdef(s: string; def: Longint): Longint;
Returns string s, transformed to integer value. If this string is not allowed integer, then value by default def is returned.

function copy(s: string; ifrom, icount: Longint): string;
Returns string that is sub-string of string S, starting from S[ifrom] and containing icount number of symbols.

function pos(substr, s: string): Longint;
Returns position (index) of first meeting subsrt in S. If S doesn’t contain Substr, 0 is returned.
procedure delete(var s: string; ifrom, icount: Longint);
Deletes from string S icount number of symbols from position ifrom.

procedure insert(s: string; var s2: string; ipos: Longint);
Inserts string s into s2, from position ipos.

function StrToFloat(s: string): Extended;
Function returns real number (with floating point), transformed from s.

function FloatToStr(e : Extended) : String;
Returns string, this string is transformed value of e.

function Padl(s : string; I : longInt) : string;
Returns string s, added with “spaces” to the length of I on the left part.
function Padr(s : string; I : longInt) : string;
Returns string s, added with “spaces” to the length of I on the right part.
function Padz(s : string; I : longInt) : string;
Returns string s, added with symbols ‘0’ to the length of I on the left part.
function Replicate(c : char; I : longInt) : string;
function StringOfChar(c : char; I : longInt) : string;
Returns string, that consists of I symbols ‘C’.
function FormatFloat(const Mask: string; d : Extended) : String;
Returns string, that consists of value d transformed with the help of mask Mask.
