pub.math:addFloats
WmPublic. Adds one floating point number (represented as a String) to another and returns the sum.
Input Parameters
num1
String Number to add.
num2
String Number to add.
precision
String Optional. Number of decimal places to which the sum will be rounded. The default value is null.
The precision parameter, if specified, will override the behavior set by the watt.server.math.floatOperation.mode property. For information about the watt.server.math.floatOperation.mode property, see the webMethods Integration Server Administrator’s Guide.
Output Parameters
value
String Sum of the numbers in num1 and num2. If a sum cannot be produced, value contains one of the following:
Value
Description
Infinity
The computation produces a positive value that overflows the representable range of a float type.
-Infinity
The computation produces a negative value that overflows the representable range of a float type.
0.0
The computation produces a value that underflows the representable range of a float type (for example, adding a number to infinity).
NaN
The computation produces a value that cannot be represented as a number (for example, any operation that uses NaN as input, such as 10.0 + NaN = NaN).
Usage Notes
Make sure the strings that are passed to the service in num1andnum2 are in a locale-neutral format (that is, using the pattern -####.##). Passing locally formatted strings may result in unexpected results. For example, calling pub.math:addFloats in a German locale with the arguments 1,23 and 2,34 will result in the value 357, not 3.57 or 3,57.
Use the watt.server.math.floatOperation.mode property to specify whether the pub.math:addFloats service return the exact result of an operation involving two floating point numbers, the result as calculated by the JVM, or the result based on a fixed number of decimal places. For information about the watt.server.math.floatOperation.mode property, see the webMethods Integration Server Administrator’s Guide.
