Build a math expression by combining operators, functions and numbers you type with fields you drag and drop in. Place number fields anywhere in the expression where there can be a number. At runtime, the expression is evaluated using the values of the fields to generate a single _output_ number.
Operators you can use are:
+ for addition
- for subtraction (or negative)
* for multiply
/ for divide
^ for power, e.g. 10^2 = 100
% for remainder/modulo, e.g. 12%5 = 2
! for factorial, e.g. 3! = 6
# allows you to add a comment to your expression (anything you type after the # is ignored when the expression is evaluated)
Use parentheses to group operations so they calculate together first.
You can also use standard math functions (with arguments inside parentheses), including:
abs - absolute value - e.g. abs(-10) returns 10
ceil - rounds up to the nearest integer
floor - rounds down to the nearest integer
min - the smallest of a comma separated list of numbers
max - the largest of a comma separated list of numbers
round - rounds to the nearest integer
random - a random number between 0 and a given value, or 1 if followed by empty parentheses - e.g. random(10) or random()
exp - e to the power of a given value
log - the logarithm using base e of a value
log10 - the logarithm using base 10 of a value
pow - the first parameter to the power of the second parameter, e.g. pow(2,3) = 8
sqrt - the square root of a value
pi - the value for pi (use without parentheses)
sin - the sine of an provided angle in radians
cos - the cosine of an provided angle in radians
tan - the tangent of an provided angle in radians
asin - the arcsine of a value between -1 and 1
acos - the arccosine of a value between -1 and 1
atan - the arctangent of a value between -1 and 1
sinh - the hyperbolic sine of a value between -1 and 1
cosh - the hyperbolic cosine of a value between -1 and 1
tanh - the hyperbolic tangent of a value between -1 and 1
You can combine multiple operations, such as:
(pi*(max(10,11,12)^2))+round(random(5))
And number fields (i.e. dropping an output from a previous card into the middle of a calculation) can be used in place of any number value.
For binary arithmetic, use & (bitwise and), ~ (bitwise not), | (bitwise or), ^| (bitwise xor), << (left shift), and >> (right shift).
Input Fields
The function has one large input area that accepts a combination of numbers, operators, and math functions you type with number fields you drag/drop in.
Output Fields
output - the number that results from evaluating the expression using the values of the fields at runtime.
