43 does floating point interval arithmetic.
58 There are 26 interval valued variables ``A'' through ``Z''
62 the (floating or interval) value.
69 This structure is given a type name, INTERVAL, by using
79 division by an interval containing 0, and an interval presented in
86 keep track of the type (e.g. scalar or interval) of intermediate
88 Note that a scalar can be automatically promoted to an interval if
89 the context demands an interval value.
100 Notice that the 2.5 is to be used in an interval valued expression
105 tokens to decide whether to convert a scalar to an interval.
106 This problem is evaded by having two rules for each binary interval
108 the left operand is an interval.
109 In the second case, the right operand must be an interval,
146 typedef struct interval {
148 } INTERVAL;
150 INTERVAL vmul(), vdiv();
155 INTERVAL vreg[ 26 ];
173 %type <vval> vexp /* interval expression */
223 printf( "interval out of order\en" );
309 INTERVAL hilo( a, b, c, d ) double a, b, c, d; {
310 /* returns the smallest interval containing a, b, c, and d */
328 INTERVAL vmul( a, b, v ) double a, b; INTERVAL v; {
332 dcheck( v ) INTERVAL v; {
334 printf( "divisor interval contains 0.\en" );
