[xsl] Magic numbers

[Yago Alvarado <Yago.Alvarado@xxxxxxxxxxxxxx>]

Hi everyone!

    I have the following xsl code:


<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="text"/>

<xsl:template match="/">
 <xsl:value-of select="100 * .05"/>
</xsl:template>

</xsl:stylesheet>



which works fine and shows the expected result... now...if you change
.05 for .07 you get something totally unexpected (at least is unexpected
to me).

My first thought was blaming the XSLT processor so I tried with another
one...
and I'm getting the same result whatever the processor is...
(MSXML 4 or Saxon 6.5.2)

   This only happens using the *magic* number of 7 with any other number it
works just fine and returns the expected result.

Does anyone know why this is happening?
Is is number 7 a truly magical number with undiscovered mathematical powers
or is it just me not understanding what's going on here? 
(my vote goes to the second one) ;-)



Regards,
Yago
