Overload 1: function Max(const X: TCplx; const Y: TCplx): TCplx;

Maximum of two numbers.

#	Name	Type	Description
1	X	TCplx
2	Y	TCplx

Returns: TCplx (complex) - the maximum of two complex numbers X and Y.

Remarks:

Complex numbers are first compared by the absolute value. If they are equal they are further compared by the unwrapped phase -PI,PI angle.

Overload 2: function Max(const X: TSCplx; const Y: TSCplx): TSCplx;

#	Name	Type	Description
1	X	TSCplx
2	Y	TSCplx

Returns: TSCplx

Overload 3: function Max(X: Double; Y: Double): Double;

Maximum of two real numbers X and Y.

#	Name	Type	Description
1	X	Double	scalar
2	Y	Double	scalar

Returns: Double - the maximum of two real numbers X and Y.

See Also: Math387.Min

Overload 4: function Max(X: Double; Y: Integer): Double;

#	Name	Type	Description
1	X	Double	scalar
2	Y	Integer

Returns: Double

Overload 5: function Max(X: Integer; Y: Double): Double;

Mixed integer/double Max/Min.

#	Name	Type	Description
1	X	Integer
2	Y	Double	scalar

Returns: Double

Remarks:

Delphi promotes the Integer arg to double, but the emitted C++ sees Max(int, double) as AMBIGUOUS between the Integer and double overloads (neither is an exact match). These exact mixed overloads resolve it; in Delphi and C# an exact match wins over the promotion, so no existing call changes.

Overload 6: function Max(X: Integer; Y: Integer): Integer;

Maximum of two integer numbers X and Y.

#	Name	Type	Description
1	X	Integer
2	Y	Integer

Returns: Int32 - the maximum of two integer numbers X and Y.

Examples

Uses MtxVecInt;

procedure Example;
var a: TVecInt;
max, ind: integer;
begin
    CreateIt(a);
    try
        a.SetIt([1,2,3,4]);
        max := a.Max(ind); // max=4, ind = 3
    finally
        FreeIt(a);
    end
end;

Overload 7: function Max(X: Integer; Y: Int64): Int64;

#	Name	Type	Description
1	X	Integer
2	Y	Int64

Returns: Int64

Overload 8: function Max(X: Int64; Y: Integer): Int64;

Mixed 64/32-bit integer Max/Min.

#	Name	Type	Description
1	X	Int64
2	Y	Integer

Returns: Int64

Remarks:

Delphi auto-promotes the 32-bit arg to Int64, but the emitted C++ would see Max(long long, int) as AMBIGUOUS between the int and Int64 overloads. These exact overloads resolve it; in Delphi and C# an exact match wins over the promotion, so no existing call changes.

Overload 9: function Max(X: Int64; Y: Int64): Int64;

Maximum of two 64bit integer numbers X and Y.

#	Name	Type	Description
1	X	Int64
2	Y	Int64

Returns: Int64 - the maximum of two 64bit integer numbers X and Y.

#	Name	Type	Description
1	X	Single
2	Y	Single

Returns: Single

Overload 11: function Maxf(X: Single; Y: Single): Single;

#	Name	Type	Description
1	X	Single	scalar
2	Y	Single	scalar

Returns: Single
