Where Is Maths Used ?
- When you do
Variable Set and click the Do Maths checkbox
- With the
If action, if you select a mathematical comparison like < or =
- With individual action conditions when a mathematical comparison is selected

Functions
Functions take their argument in parenthesis e.g. sin(90)
- abs - absolute value
- acos - arc cosine; the returned angle is in the range 0.0 through pi
- asin - arc sine; the returned angle is in the range -pi/2 through pi/2
- atan - arc tangent; the returned angle is in the range -pi/2 through pi/2
- cbrt - cube root
- ceil - smallest value that is greater than or equal to the argument and is an integer
- cos - trigonometric cosine
- cosh - hyperbolic cosine
- exp - Euler's number e raised to the power of the value
- expm1 - ex-1
- floor - largest value that is less than or equal to the argument and is an integer
- getExp - unbiased exponent used in the representation of val
- log - natural logarithm (base e)
- log10 - base 10 logarithm
- log1p - natural logarithm of (val+1)
- nextup - floating-point value adjacent to val in the direction of positive infinity
- round - closest 64 bit integer to the argument
- roundhe - double value that is closest in value to the argument and is equal to a mathematical integer, using the half-even rounding method.
- signum - signum function of the argument; zero if the argument is zero, 1.0 if the argument is greater than zero, -1.0 if the argument is less than zero
- sin - trigonometric sine
- sinh - hyperbolic sine
- sqrt - correctly rounded positive square root
- tan - trigonometric tangent
