Maths

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

What's Available

Operators

• + - * / - the basic operators
• % - modulus
• ^ - power

Constants

• E - the base of the natural logarithms
• EUL - Euler's Constant
• LN2 - log of 2 base e

Functions

Trigonometric functions expect a value in radians.

Functions take their argument in parenthesis e.g. sin(torad((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
• tanh - hyperbolic tangent
• todeg - converts an angle measured in radians to an approximately equivalent angle measured in degrees
• torad - converts an angle measured in degrees to an approximately equivalent angle measured in radians
• ulp - size of an ulp of the argument
