function acscd( x ) {
	var rad = acsc( x );
	return rad2deg( rad );
}
Computes the arccosecant (in degrees) of a double-precision floating-point number.

@param {number} x - input value
@returns {number} arccosecant (in degrees)

@example
var v = acscd( Infinity );
// returns 0.0

@example
var v = acscd( 2 * Math.sqrt( 3 ) / 3 );
// returns ~60.0

@example
var v = acscd( Math.sqrt( 2 ) );
// returns ~45.0

@example
var v = acscd( 2 );
// returns ~30.0

@example
var v = acscd( 1 );
// returns 90.0

@example
var v = acscd( NaN );
// returns NaN
