function bernoullif( n ) {
	return addon( n );
}
Computes the nth Bernoulli number as a single-precision floating-point number.

@private
@param {NonNegativeInteger} n - the Bernoulli number to compute
@returns {number} Bernoulli number

@example
var y = bernoullif( 0 );
// returns 1.0

@example
var y = bernoullif( 1 );
// returns 0.5

@example
var y = bernoullif( 2 );
// returns ~0.167

@example
var y = bernoullif( 3 );
// returns 0.0

@example
var y = bernoullif( 4 );
// returns ~-0.033

@example
var y = bernoullif( 5 );
// returns 0.0

@example
var y = bernoullif( 20 );
// returns ~-529.124

@example
var y = bernoullif( 66 );
// returns Infinity

@example
var y = bernoullif( 68 );
// returns -Infinity
