Yet another category which has no direct support in XSLT v1.0 or XSLT v2.0!
However, given the strong support for scientific functions in .NET, it’s easy to call
out to .NET classes, which is exactly what every single one of the functoids in this
category does.
Having said that: have you ever used one of these functoids in a map? Care to share
a real world example?
I’d be interested to find out how often they are used.
For each functoid I’ve shown:
- Whether XSLT or C# is emitted
- Whether an XSLT equivalent exists
- The XSLT or C# emitted by the functoid
- Where C# is emitted, the equivalent XSLT to achieve the same functionality (in both
XSLT v1.0 and v2.0)
Functoids covered in this category:
| 10^n | Natural Logarithm |
| Arc Tangent | Sine |
| Base-Specified Logarithm | Tangent |
| Common Logarithm | X^Y |
| Cosine | Common Code |
| Natural Exponential Function |
