{{alias}}( value )
    Tests if a value is a triangular number.

    Return values are not reliable for numbers greater than 1125899906842624.

    Parameters
    ----------
    value: any
        Value to test.

    Returns
    -------
    bool: boolean
        Boolean indicating whether value is a triangular number.

    Examples
    --------
    > var bool = {{alias}}( 36.0 )
    true
    > bool = {{alias}}( new Number( 36.0 ) )
    true
    > bool = {{alias}}( 3.14 )
    false
    > bool = {{alias}}( -5.0 )
    false
    > bool = {{alias}}( null )
    false


{{alias}}.isPrimitive( value )
    Tests if a value is a number primitive which is a triangular number.

    Parameters
    ----------
    value: any
        Value to test.

    Returns
    -------
    bool: boolean
        Boolean indicating whether value is a number primitive which is a
        triangular number.

    Examples
    --------
    > var bool = {{alias}}.isPrimitive( 36.0 )
    true
    > bool = {{alias}}.isPrimitive( new Number( 36.0 ) )
    false


{{alias}}.isObject( value )
    Tests if a value is a number object having a value which is a triangular
    number.

    Parameters
    ----------
    value: any
        Value to test.

    Returns
    -------
    bool: boolean
        Boolean indicating whether value is a number object having a value which
        is a triangular number.

    Examples
    --------
    > var bool = {{alias}}.isObject( 36.0 )
    false
    > bool = {{alias}}.isObject( new Number( 36.0 ) )
    true
