Built in Operators and Functions

The following lists show the built-in operators and functions that are included in dotMath. You can further extend the functionality of dotMath by adding your own functions and registering them with dotMath before compiling. Check out Getting Started to learn more.

Standard Operators

Operator	Description
+	Addition
-	Subtraction
*	Multiplication
/	Division
%	Modulus (returns the remainder of a division operation)
^	Exponent (x^y = xy)

Binary Operators

Operator	Description
==	Returns 1 if both sides are equal.
!=	Returns 1 if the left side is not equal to the right.
<>	Returns 1 if the left side is not equal to the right.
<	Returns 1 if left side is less than the right.
>	Returns 1 if left side is greater than the right.
<=	Returns 1 if the left side is less than or equal to the right.
>=	Returns 1 if the left side is greater than or equal to the right.
&&	Returns 1 if both sides are true.
||	Returns 1 if either side is true.

Functions

Function	Description
abs	Absolute value of a specified value or expression.
acos	Returns the angle whose cosine is the specified number.
asin	Returns the angle whose sin is the specified number.
atan	Returns the angle whose tangent is the specified number.
ceiling	Returns the smallest whole number greater than or equal to the specified number.
cos	Returns the cosine of the specified angle.
cosh	Returns the hyperbolic cosine of the specified angle.
exp	Returns e raised to the specified power.
floor	Returns the largest whole number less than or equal to the specified number.
log	Returns the logarithm of the specified number.
log10	Returns the base 10 logarithm of the specified number.
round	Returns the value nearest the specified value.
sign	Returns a value indicating the sign of the specified value.
sin	Returns the sine of the specified angle.
sinh	Returns the hyperbolic sine of the specified angle.
sqrt	Returns the square root of the specified number.
tan	Returns the tangent of the specified angle.
tanh	Returns the hyperbolic tangent of the specified angle.
min	min(expr1, expr2) Returns the minimum value among 2 elements.
max	max(expr1, expr2) Returns the maximum value among 2 elements.
if	if(binaryExpression, trueExpression, falseExpression) If the value of binaryExpression is true, the trueExpression evaluation is returned. Otherwise the falseExpression is returned.
