How can I calculate the absolute value of a number in XSLT?

Question

I have

<xsl:value-of select="DifferenceInDays" />

DifferenceInDays can be negative or positive, I want to display it as positive. How can I do this?

Answer 1

Got it, does the trick.

Answer 2

This can be achieved using the xpath abs function.

<xsl:value-of select="abs(DifferenceInDays)"/>

Answer 3

In XPath 1.0 (XSLT 1.0) use the following expression:

   $vNum*($vNum >=0) - $vNum*($vNum < 0)

In XPath 2.0 (XSLT 2.0) use the abs() function.

Answer 4

diffInDays * (1 - 2*(diffInDays < 0))
