Table 1 provides a description of each function of the library. For each function the evaluation time of execution is measured. The measurement was made on a system with the following parameters: Athlon 64 3000 + (ALTLinux 3.0 (32bit)), by measuring the total time of execution of the function, while calling it 1000 times.

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.
