If we're going to be making changes in that paragraph, let's also fix http://www.boyd.com/1364_btf/report/full_pr/463.html -- Brad -----Non-member submission from [Will Adams <wadams@freescale.com>]----- Date: Wed, 02 Aug 2006 11:50:03 -0500 I have made a number of suggestions for changing section 5.1.13 `Conditional operator'. In the interests of clarity, below is my suggested rewrite of this section. will adams 5.1.13 Conditional operator The conditional operator, a ternary operator, shall be right associative and its three operands shall be separated by symbols `?' and `:' in the format given in Syntax 5-1. [Insert Syntax 5-1 from the current definition.] The evaluation of a conditional operator shall begin with a logical inequality comparison (see 5.1.8) of expression1 with zero, termed the `condition'. If the condition evaluates to false (0), then expression2 shall not be evaluated, and expression3 shall be evaluated and its result used as the result of the conditional expression. If the condition evaluates to true (1), then expression3 shall not be evaluated, and expression2 shall be evaluated and its result used as the result of the conditional expression. If the condition evaluates to an ambiguous value (x), then both expression2 and expression3 shall be evaluated, and their results shall be combined, bit by bit, using Table 5-21 to calculate the final result, unless expression2 or expression3 is real, in which case the result shall be 0. If the lengths of expression2 and expression3 are different, the shorter operand shall be lengthened to match the longer and zero-filled from the left (the high-order end). [Insert Table 5-21 and the example from the current definition.]Received on Wed Aug 2 10:00:24 2006
