https://www.w3.org/Bugs/Public/show_bug.cgi?id=28845 --- Comment #4 from Michael Kay <mike@saxonica.com> --- We walked through test case numberformat135 in the WG as follows. The test is fn:format-number(0.2, '#.e9') 4.7.4 Analyzing the picture string: * integer-part-grouping-positions = empty set * minimum-integer-part-size = 1 * prefix = "" * fractional-part-grouping-positions = empty set * minimum-fractional-part-size = 0 * maximum-fractional-part-size = 0 * minimum-exponent-size = 1 * suffix = "" 4.7.5 Formatting the number 1. If the input number is NaN - N/A 2. The positive sub-picture is used if the input number is positive 3. If the sub-picture contains a percent-sign: N/A 4. If the minimum exponent size is non-zero, then the adjusted number is scaled to establish a mantissa and an integer exponent. mantissa = 0.2, exponent = 0 5. The mantissa is converted (if necessary) to an xs:decimal value: no conversion needed. 6. The absolute value of the rounded number is converted to a string in decimal notation: ".2". ** Here I think we went wrong. We missed the sentence "This value is then rounded so that it uses no more than maximum-fractional-part-size digits in its fractional part. " Corrected result: "." 7. If the number of digits to the right of the decimal-separator-sign is less than minimum-fractional-part-size: N/A 8. For each integer N in the integer-part-grouping-positions list: no action 9. For each integer N in the fractional-part-grouping-positions list: no action 10. If there is no decimal-separator-sign in the sub-picture, or if there are no digits to the right of the decimal-separator-sign character in the string: Original analysis: N/A. Corrected analysis: The string is now "". 11. If an exponent exists, then the string produced from the mantissa as described above is extended with the following, in order: (a) the exponent separator sign; (b) if the exponent is negative, the minus sign; (c) the value of the exponent represented as a decimal integer, extended if necessary with leading zeroes to make it up to the minimum exponent size, using digits taken from the decimal digit family. => ".2e0" Corrected analysis: "e0" 12. The result of the function is the concatenation of the appropriate prefix, the string conversion of the number as obtained above, and the appropriate suffix. => .2e0. Corrected analysis: "e0" A strange result perhaps, but you get what you ask for. -- You are receiving this mail because: You are the QA Contact for the bug.Received on Friday, 17 July 2015 16:05:06 UTC
