RE: Math: Removing X number of zeroes from number Y.

2005-06-06 07:41:43

I have a fare element that is returned as, for example, 
79000. The decimal point value is specified in another 
element as for example 2. Therefore the number should be: 790.00

There's a way to do this mathematically:

Where x=DecimalPoint, and y=fare, the forumla would be y/(10^x)

But as far as I know there's no exponential function in XSLT 
1.0. I'm using, or rather, _have_ to use MSXML, I can't go 
for FXSLT, etc.

It's worth mentioning that fare is of type 'double' and 
DecimalPoint is of type 'short'

Anyone have any ideas on how to do this in plain XSL ? 


<xsl:value-of select="concat(substring(.,0,string-length(.) - $dp + 1),
'.', substring(.,string-length(.) - $dp + 1))"/>

$dp is the number of decimal places.
