Double.IsInfinity

Syntax

IsInfinity(Value: Double): Boolean;

Parameters

Value - checked real value.

Description

The IsInfinity method checks if the value of the variable is equivalent to positive or negative infinity. If the variable value is equivalent to any, the method returns True, otherwise it returns False.

Example

Sub Main;

Var

B: Boolean;

D: Double;

Begin

D := Double.PositiveInfinity;

B := Double.IsInfinity(d);

End Sub Main;

After executing the example the "B" variable will contain the attribute that determines whether the value of the "D" variable is equivalent to positive or negative infinity, that is, to the value 1.#INF or -1.#INF.
