Arithmetic Operators
These are the operators you're most familiar with. They work just as you'd expect.
| Operator | Behavior |
|---|---|
| + a, plus a | Positive a |
| - a, minus a | Negative a |
| a + b, a plus b | Adds a and b |
| a - b, a minus b | Subtracts b from a |
| a × b, a x b, a * b | Multiplies a and b |
| a / b, a ÷ b | Divides a by b |
| a^b | Raises a to the power b |
| a mod b | Remainder of a / b |
Arithmetic operators apply to both numbers and units. You can also use superscript numbers like 2 m² to do power operations.
23 m/s + 12 m/s
15 × 2 ÷ 3
2^3 == 2³
7 mod 335 m/s
10
true
1Assignment Operator
The = operator is used to assign a value to a name. If you need to check the equality of two values, use == instead. For more detail on assignment of values, see Variables.
You can assign new values to variables by using the assignment operator again.
dinner cost = $25
// Don't forget to tip!
dinner cost = $25 + 18%$25
$29.50Arithmetic Assignment Operators
The arithmetic operators can be combined with the assignment operator = as a convenient way to change a value.
| Operator | Behavior |
|---|---|
| a += b | Add b to a and assign the result to a |
| a -= b | Subtract b from a and assign the result to a |
| a ×= b, a *= b | Multiply a and b, then assign the result to a |
| a /= b, a ÷= b | Divide a by b, then assign the result to a |
| a ^= b | Raise a to the power of b and assign the result to a |
value = 10
value += 5
value -= 10
value ×= 2
value /= 5
value ^= 310

8Percentages
You can apply percentages using the % operator after a value. Percentages are just numbers, but they also have some special abilities. Figures lets you add and subtract percentages.
20 + 50%
100 meters - 10%
50 + 10% == 50 + (50 * .1)30
90 m
trueFigures also understands some common phrases related to percentages.
20% of $10
5% off 100 feet
15% on 50$2
95 ft
57.5When combined with other percentages, they add and subtract normally.
20% + 30%
50% - 10%50%
40%When multiplying and dividing, percentages are treated as fractions.
20 × 10%
5 / 25% == 5 / 0.252
trueComparison Operators
Values can be compared to each other. Comparison operators generate boolean (true or false) answers.
| Operator | Behavior |
|---|---|
| a == b | a is equal to b |
| a > b | a is greater than b |
| a >= b | a is greater than or equal to b |
| a < b | a is less than b |
| a <= b | a is less than or equal to b |
32 == 16 × 2
15 m > 15 m
15 m >= 15 m
20 < infinitytrue
false
true
trueOnly numbers can be compared. If they have associated units, the units must be of the same kind.
32 > 15 m // first value has no unit
15 ft > 20 inches
25 km > 18 sec // different kinds of units
true == false
true > false // only valid for numbers●
true

false
●Logical Operators
Boolean values (true and false) can be combined using logical operations.
| Operator | Behavior |
|---|---|
| a && b, a and b | Both a and b are true |
| a || b, a or b | Either a or b is true |
| !a, ¬a | Reverse a's value (e.g. true becomes false) |
true and false
true or false
!false and (3 > 2)false
true
trueRange Operator
Figures can represent any range of numbers between two values.
| Operator | Behavior |
|---|---|
| a .. b | A range of numbers from a to b, including a and b |
| a .. b step c | A range of numbers from a to b, including a and b, separated by c |
By default the step value is 1.
See ranges for more on how to use number ranges.
Other Operators
Factorial
A factorial is a function that multiplies an integer (whole number) by all the positive integers below it. The factorial operator ! goes after the value.
3! // 3 × 2 × 1
5! // 5 × 4 × 3 × 2 × 1
-2!
1.5!6

●Multiple Statements
If you want to calculate more than one thing on a single line, separate the computations with a terminator ;. Both calculations are executed, but you'll only see the results of the last one.
3 + 2; 42 + 12
value = 5; value × 354
