Float A – Specifies float operand A.

Float B – Specifies float operand B.

Mode – Determines what output to use when no output parameter is specified. It is useful if the type of the operation needs to be animated.

Product – Performs a multiplication operation and returns the product (A*B).
Ratio – Performs a division operation and returns the ratio (A/B).
Sum – Performs an addition operation and returns the sum (A+B).
Difference – Performs a subtraction operation and returns the difference (A-B).
Power – Performs an exponentiation operation and returns the power (A^B).
Sin – Performs a sine function and returns the result (sin(A)).
Cos – Performs a cosine function and returns the result (cos(A)).
Min – Performs a comparison and returns the minimum value.
Max – Performs a comparison and returns the maximum value.
Abs – Returns the absolute value of the first argument (absA).
Ceil – Performs a ceiling function that rounds up to the next integer that is equal to or greater than the largest argument - A or B (ceil(A)); (ceil(B)).
Exp – Performs an exponential function (e^a+b).
Floor – Performs a floor function that rounds down to the next integer that is equal to or smaller than the smallest argument - A or B (floor(A)); (floor(B)).
Log – Performs a natural logarithmic function (ln(A)).
Log 10 – Performs a common logarithmic function (base 10) on the first argument (log(A)).
Sqrt – Performs a square root function with the first argument (√A)
Fmod – Performs a division operation and returns the remainder (A%B).
Average – Returns the average of A and B ((A+B)/2).
Tan – Performs a tangent function and returns the result (tan(A.0)).
Asin – Performs an arcsine function and returns the result (asin(A).
Acos – Performs an arccosine function and returns the result (acos(A)).
Atan – Performs an arctangent function and returns the result (atan(A)).
Atan 2 – Performs an arctangent function with two arguments and returns the result (atan2(A,B)).
