question: protected static boolean approxUnit ( final StringBuilder sbuf , final int amount , final int size , final String name ) { int count = amount / size ; int remainder ; if ( count == 0 ) { return false ; } remainder = amount - ( count * size ) ; if ( remainder >= ( size * 95 / 100 ) ) { count ++ ; sbuf . append ( count ) ; } else if ( remainder >= ( size * 3 / 4 ) ) { count ++ ; sbuf . append ( "just under " ) ; sbuf . append ( count ) ; } else if ( remainder >= ( size * 1 / 4 ) ) { sbuf . append ( "about " ) ; sbuf . append ( count ) ; sbuf . append ( " and a half" ) ; count = 2 ; } else if ( remainder >= ( size * 5 / 100 ) ) { sbuf . append ( "just over " ) ; sbuf . append ( count ) ; } else { sbuf . append ( count ) ; } sbuf . append ( ' ' ) ; sbuf . append ( Grammar . plnoun ( count , name ) ) ; return true ; }
target:  For a given amount and unit size, generate the approximate value.
