The Math folder in the control block palette contains blocks that perform mathematical functions on one or more inputs, producing a single output. The number of inputs to a Math block depends on the number of inputs supported by the type of math function. The Logic View allows you to add multiple connections to the output of the block.

The Math primitive provides the following reliability values: Math Overflow, Math Underflow, Divide by zero, Not a number, Math Error.

Table 1. Math Blocks
Type	Description	Inputs (Float) ¹	Outputs (Float)¹
Absolute Value	Absolute Value	I1	Present Value
ACOS ²	Arc Cosine	I1	Present Value
Add	Add	I1 I2	Present Value
ASIN²	Arc Sine	I1	Present Value
ATAN²	Arc Tangent	I1	Present Value
COS²	Cosine	I1	Present Value
Divide	Divide (I1/I2)	I1 I2	Present Value
Exp	Exponent (e^l1)	I1	Present Value
LOG	Natural Log (LN, LOG_e, or LOG base e)	I1	Present Value
LOG10	LOG10	I1	Present Value
Multiply	Multiply	I1 I2	Present Value
Negate	Negative	I1	Present Value
Power	Power (I1^I2)	I1 I2	Present Value
Round	Rounds to nearest 1s	I1	Present Value
SIN²	Sine	I1	Present Value
SQRT	Square Root	I1	Present Value
Subtract	Subtract	I1 I2	Present Value
TAN²	Tangent	I1	Present Value

¹ The inputs and outputs of this block are exposed for connection by default.

² This block uses radians instead of degrees. To convert from degrees to radians, multiply the value by 0.0174533, that is, pi/180.
