Scientific Functoids Reference

 

Use Scientific functoids to perform a variety of standard trigonometric, logarithmic, and exponential calculations.

Important

Because Microsoft BizTalk Server uses the underlying functionality of the .NET Framework, the results produced by some of the Scientific functoids may vary from the equivalent functoids in earlier versions of BizTalk Server. For example, very large values returned as output of these functoids may be returned as "Infinity" rather than an exponential value. You should test your maps thoroughly to ensure that you are getting the results you expect.

When a Scientific functoid determines that one or more of its input parameters is not valid, it cancels the operation and returns an empty string, such that a field in an output instance message is created as "<FieldName></FieldName>" and the string Size functoid returns zero (0).

When the input parameter descriptions specify a numeric value, strings that can be interpreted as numbers are also accepted.

For conceptual information about Scientific functoids, see Scientific Functoids.

The following table shows the functoids in the Scientific category.

Scientific functoid	Description
10^n	Returns the number 10 raised to a specified power.
Arc Tangent Functoid	Returns the arc tangent of a number.
Base-Specified Logarithm	Returns the base-specified logarithm of a value.
Common Logarithm	Returns the base 10 logarithm of a value.
Cosine	Returns the cosine of an angle.
Natural Exponential Function	Returns e raised to a specified power.
Natural Logarithm	Returns the base e logarithm of a value.
Sine	Returns the sine of an angle.
Tangent	Returns the tangent of an angle.
X^Y	Raises a specified value to the power of another specified value.
