IBM webMethods Rules Development provides predefined math functions as listed in the following table:
| Function | Returns | Description |
|---|---|---|
| long abs(long value) | Integer | Returns the absolute value of the specified long value. |
| double abs(long double) | Integer | Returns the absolute value of the specified double value. |
| double acos(double val) | Integer | Returns the arc cosine of the specified double value. |
| double asin(double val) | Integer | Returns the arc sine of the specified double value. |
| double atan(double val) | Integer | Returns the arc tangent of the specified double value. |
| double ceil(double val) | Integer | Returns the smallest integer that is greater than or equal to the specified double value. |
| double cos(double val) | Integer | Returns the trigonometric cosine of the specified angle. |
| double cosh(double val) | Integer | Returns the hyperbolic cosine of the specified double value. |
| double degreesToRadians(double angdeg) | Integer | Returns an approximately equivalent angle measured in radians for the specified angle measured in degrees. |
| double exp(double val) | Integer | Returns Euler's number e raised to the power of
the specified double value. |
| double floor(double val) | Integer | Returns the largest integer that is less than or equal to the specified double value. |
| double log(double val) | Integer | Returns the natural logarithm (base e) of the specified double value. |
| long max(long val1, long val2) | Integer | Returns the larger of the two specified long values. If the specified values are equal, then the result is that same value. |
| double max(double val1, double val2) | Integer | Returns the larger of the two specified double values. If the specified values are equal, then the result is that same value. |
| long min(long val1, long val2) | Integer | Returns the lesser of the two specified long values. If the specified values are equal, then the result is that same value. |
| double min(double val1, double val2) | Integer | Returns the lesser of the two specified double values. If the specified values are equal, then the result is that same value. |
| long mod(long val1, long val2) | Integer | Returns the remainder of two long values. The remainder is obtained
when dividing val1 by val2. |
| double mod(double val1, double val2) | Integer | Returns the remainder of two double values. The remainder is
obtained when dividing val1 by val2. |
