function minabsf( x, y ) {
	return minf( absf( float64ToFloat32( x ) ), absf( float64ToFloat32( y ) ) );
}
Returns the minimum absolute single-precision floating-point number.

@param {number} x - first number
@param {number} y - second number
@returns {number} minimum absolute value

@example
var v = minabsf( -4.0, 3.0 );
// returns 3.0

@example
var v = minabsf( 3.14, NaN );
// returns NaN

@example
var v = minabsf( +0.0, -0.0 );
// returns +0.0
