question: public static final double nextDouble ( double value ) { if ( value == Double . POSITIVE_INFINITY ) { return value ; } long bits ; if ( value == 0 ) { bits = 0 ; } else { bits = Double . doubleToLongBits ( value ) ; } return Double . longBitsToDouble ( value < 0 ? bits - 1 : bits + 1 ) ; }
target:  Returns the double value which is closest to the specified double but larger.
