C#

public Sech()

Fields

FunctionName

The name of the function.

C#

public static readonly string FunctionName

Properties

FunctionInfo

Metadata describing the function signature, category, and argument requirements.

C#

public override FunctionInfo FunctionInfo { get; }

Property Value:

The function info as FunctionInfo.

Overrides: FunctionBase.FunctionInfo

Name

The function name "SECH" as it appears in spreadsheet formulas.

C#

public override string Name { get; }

Property Value:

The name as String.

Overrides: FunctionBase.Name

Methods

EvaluateOverride(FunctionEvaluationContext<double>)

Evaluates the SECH function and returns the hyperbolic secant, checking for values that would cause numerical overflow.

protected override RadExpression EvaluateOverride(FunctionEvaluationContext<double> context)

Parameters:contextFunctionEvaluationContext<double>

The context.

Returns:

Functions result as RadExpression.
