/// <summary>
/// Creates a leaf condition node that represents a comparison of property value and Floating Point value.
/// </summary>
/// <param name="propertyName">The name of a property to be compared, or null for an unspecified property.
/// The locale name of the leaf node is LOCALE_NAME_USER_DEFAULT.</param>
/// <param name="value">The Floating Point value against which the property value should be compared.</param>
/// <param name="operation">Specific condition to be used when comparing the actual value and the expected value of the given property</param>
/// <returns>SearchCondition based on the given parameters</returns>
/// <remarks>
/// The search will only work for files that are indexed, as well as the specific properties are indexed. To find
/// the properties that are indexed, look for the specific property's property description and
/// <see cref="P:Microsoft.WindowsAPICodePack.Shell.PropertySystem.ShellPropertyDescription.TypeFlags"/> property for IsQueryable flag.
/// </remarks>
