[ to all - sorry for the previous post - it got away before i was finished ] Thanks Jeff and Stuart for the info and suggestions: I think you are right on, Jeff when you suggested: > what you are seeing is IEEE-754 round to nearest mode, > which says that ties are broken by rounding to an even value When I get 107.5, it rounds up to 108, when I get 106.5 it rounds down to 106. I am loathe to use the rounding option because: 1. some of the numbers submitted to this template will have more decimal places (i.e. 1.065 --> result = 1.07) 2. i have tried multiplying by 100, then rounding, then dividing by 100 to solve [#1] for 2 decimal places, but occasionally get strange values from the division, like 1.0649999999999999999999999999999999. Pending a better solution, I have implemented a dreadful kludge - <xsl:value-of select="format-number($number +.000000001 ,$format)"/> This causes 106.500000001 to round up to 107, and 1.060000001 to round up to 1.07, but 'yuk'.

This will work, and solve his problem, but the spec is clear that format-number() should do that for him. The XSLT 2.0 spec has the gory details, as does the Java spec referenced in the XSLT 1.0 spec. -- Jeff Kenton DataPower Technology, Inc. **** Wire speed XSLT **** XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
