Summary

Adds a function.

Pascal

 public procedure AddFunc(const AName: string; AFunc: TFloat32Func); overload;
public procedure AddFunc(const AName: string; AFunc: TFloat64Func); overload;
public procedure AddFunc(const AName: string; AFunc: TFloat80Func); overload;
public procedure AddFunc(const AName: string; AFunc: TUnary32Func); overload;
public procedure AddFunc(const AName: string; AFunc: TUnary64Func); overload;
public procedure AddFunc(const AName: string; AFunc: TUnary80Func); overload;
public procedure AddFunc(const AName: string; AFunc: TBinary32Func); overload;
public procedure AddFunc(const AName: string; AFunc: TBinary64Func); overload;
public procedure AddFunc(const AName: string; AFunc: TBinary80Func); overload;
public procedure AddFunc(const AName: string; AFunc: TTernary32Func); overload;
public procedure AddFunc(const AName: string; AFunc: TTernary64Func); overload;
public procedure AddFunc(const AName: string; AFunc: TTernary80Func); overload;

Parameters

Parameters	Description
const AName: string	Identifier for the function.
AFunc: TFloat32Func	Function pointer that evaluates the function.

Description

Adds a function to the internal context. Multiple calls to the same function with the same parameters might be resolved to a single call during common sub-expression elimination (CSE) optimization. A possible workaround would be to add a fake extra parameter and pass in different constant for each distinct call.

Notes

Any functions added using these methods will override identifiers of the same name in external contexts added through ExtContextSet.
