{{alias}}( n )
    Computes the nth Fibonacci number as a single-precision floating-point
    number.

    Fibonacci numbers follow the recurrence relation

        F_n = F_{n-1} + F_{n-2}

    with seed values F_0 = 0 and F_1 = 1.

    If `n` is greater than `36`, the function returns `NaN`, as larger Fibonacci
    numbers cannot be accurately represented due to limitations of single-
    precision floating-point format.

    If not provided a nonnegative integer value, the function returns `NaN`.

    If provided `NaN`, the function returns `NaN`.

    Parameters
    ----------
    n: integer
        Input value.

    Returns
    -------
    y: integer
        Fibonacci number.

    Examples
    --------
    > var y = {{alias}}( 0 )
    0
    > y = {{alias}}( 1 )
    1
    > y = {{alias}}( 2 )
    1
    > y = {{alias}}( 3 )
    2
    > y = {{alias}}( 4 )
    3
    > y = {{alias}}( 37 )
    NaN
    > y = {{alias}}( NaN )
    NaN
