Basic Usage

Type any expression. Add = at the end to see the result:

2 + 2 =
// Result: 4

100 / 4 =
// Result: 25

Operators

Operator	Description	Example
+	Addition	5 + 3 = 8
-	Subtraction	10 - 4 = 6
*	Multiplication	6 * 7 = 42
/	Division	15 / 3 = 5
^	Power	2^8 = 256
%	Modulo	17 % 5 = 2
()	Parentheses	(2 + 3) * 4 = 20

Percentages

100 + 18% =
// Result: 118

500 - 20% =
// Result: 400

what is 15% of 200 =
// Result: 30

Variables

Store values for reuse:

price = 100
quantity = 5
discount = 10

subtotal = price * quantity =
// Result: 500

discount_amount = subtotal * discount / 100 =
// Result: 50

total = subtotal - discount_amount =
// Result: 450

Functions

Function	Description	Example

tan(x)	Tangent	tan(0) = 0
log(x)	Natural log	log(e) = 1
log10(x)	Log base 10	log10(100) = 2
floor(x)	Round down	floor(3.7) = 3
ceil(x)	Round up	ceil(3.2) = 4
round(x)	Round nearest	round(3.5) = 4
min(a,b)	Minimum	min(5, 3) = 3
max(a,b)	Maximum	max(5, 3) = 5

Practical Examples

Tip Calculator

bill = 85.50
tip_percent = 18
people = 4

tip = bill * tip_percent / 100 =
// Result: 15.39

total = bill + tip =
// Result: 100.89

per_person = total / people =
// Result: 25.22

Area Calculation

radius = 5
area = pi * radius^2 =
// Result: 78.54
