Module	Name	Version	License	Source	Languages	Platforms	Type	Author	Description
FLibMath	Math functions	0.7	GPL2	spec_FLibMath.so	en,uk,ru,de	x86,x86_64,ARM	Special	Roman Savochenko   Maxim Lysenko (2009-2010) — the page translation	Provides a library of the standard mathematical functions.

The module provides OpenSCADA for a static standard mathematical functions library.

To address the functions of the library you can use the static call address Special.FLibMath.{Func}() or dynamic SYS.Special.FLibMath["{Func}"].call(), SYS.Special.FLibMath.{Func}(). Where {Func} — function identifier in the library.

1 Functions

Table 1 provides a description of each function of the library.

2 User programming API

The module, as an object, provides user programming functions.

The object "Functions library" (SYS.Special.FLibMath)

• ElTp {funcID}(ElTp prm1, ...) — call the library function {funcID}. Return result of the called function.

The object "User function" (SYS.Special.FLibMath["funcID"])

• ElTp call(ElTp prm1, ...) — call the function with parameters prm{N}. Return result of the called function.
