signum
integer signum( integer arg );
long signum( long arg );
number signum( number arg );
integer signum( decimal arg );The signum() function returns signum of the argument.
If the argument is negative, the function returns -1.
If the argument is positive, the function returns 1.
It the argument is 0, the function returns 0.
If the argument is null, the function fails.
Compatibility
The signum(integer), signum(long), signum(number) and signum(decimal) functions are available since CloverETL 3.5.0-M2.
Example 180. Usage of signum
The function signum(-2147483648)returns -1.
The function signum(-123456789012345L) returns -1.
The function signum(0.0) returns 0.
The function signum(123.45d) returns 1.
The function signum(null) fails.
sin
number sin( number angle );
number sin( decimal angle );The sin() function returns the trigonometric sine of a given angle.
The angle is in radians.
If the given argument is null, the function fails with an error.
Compatibility
The sin(decimal) and sin(number) functions are available since CloverETL 3.5.0-M2.
Example 181. Usage of sin
The function sin(0D) returns 0.0.
The function sin(pi()*0.5) returns 1.0.
The function sin(toRadians(45)) returns 0.7071067811865475.
sqrt
number sqrt( number arg );
number sqrt( decimal arg );The sqrt() function returns the square root of a given argument.
The argument can be of any numeric data type; if the argument is integer or long, the argument will be converted to the number (double).
If a given argument is null, the function fails with an error.
Compatibility
The sqrt(decimal) and sqrt(number) functions are available since CloverETL 3.0.0.
Example 182. Usage of sqrt
The function sqrt(81) returns 9.0.

The function sqrt(1.21) returns 1.1.
The function sqrt(1.44D) returns 1.2.
The function sqrt(0) returns 0.0.
the function sqrt(-1) returns null.
tan
number tan( number angle );
number tan( decimal angle );The tan() function returns the trigonometric tangent of a given angle.
The angle is in radians.
If the given argument is null, the function fails with an error.
Compatibility
The tan(decimal) and tan(number) functions are available since CloverETL 3.5.0-M2.
Example 183. Usage of tan
