Arithmetic Operators

The Arithmetic operators contain both unary and binary operations:

Unary Operators

Unary operators have two parameters: src and answer. Both of these parameters follow the syntax based upon the equation below:

{op}(src) = answer

where:

op - is the unary operation: Inverse (inv), SquareRoot (sqrt),
Power (^), etc.

src - is the input table to the operator op.

answer - contains the result if the operation is successful.

Binary Operators

Binary operators follow a syntax based upon the following equation:

lhs {op} rhs = answer

where:

op - is the binary operator: Add (+), Subtract(-), Multiply(*),
Divide (/).

lhs - is the left-hand side of the binary operator op.

rhs - is the right-hand side of the operator.

answer - contains the result if the operation is successful.

The Math library contains the following Arithmetic operators:

Adds records in lhs to rhs and stores the result in answer.

Inputs

lhs: a value table.

rhs: a value table.

Outputs

answer: a value table.

Notes

•	lhs, rhs, and answer must be of the same binding.

•	lhs, rhs, and answer must be of the same format (after promotion).

•	If lhs and rhs are both constant value tables (created by the Constant operator), no records will be added to the answer table.

•	When adding directional values such as vector and tensor, no checks are made to verify they are relative to the same system.

Expression Builder

lhs + rhs

XML Example

<call name="Add" lhs="lhs_tab" rhs="rhs_tab"

answer="ans_tab" />

Subtracts records in rhs from lhs and stores the result in answer.

Inputs

lhs: a value table.

rhs: a value table.

Outputs

answer: a value table.

Notes

•	lhs, rhs, and answer must be of the same binding.

•	lhs, rhs, and answer must be of the same format (after promotion).

•	If lhs and rhs are both constant value tables (created by the Constant operator), no records will be added to the answer table.

•	When subtracting directional values such as vector and tensor, no checks are made to verify they are relative to the same system.

Expression Builder

lhs - rhs

XML Example

<call name="Subtract" lhs="lhs_tab" rhs="rhs_tab"

answer="ans_tab" />

Multiplies records in lhs with rhs and stores the result in answer.

Inputs

lhs: a value table.

rhs: a value table.

Outputs

answer: a value table.

Notes

•	lhs, rhs, and answer must be of the same binding.

•	lhs, rhs, and answer must be of the same format (after promotion).

•	If lhs and rhs are both constant value tables (created by the Constant operator), no records will be added to the answer table.

•	If lhs and rhs are vectors or tensors, a component-wise multiplication is performed, functioning as a scale operation).

Expression Builder

lhs * rhs

XML Example

<call name="Multiply" lhs="lhs_tab" rhs="rhs_tab"

answer="ans_tab" />

Divides records in lhs by rhs and stores the result in answer.

Inputs

lhs: a value table.

rhs: a value table.

Outputs

answer: a value table.

Notes

•	lhs, rhs, and answer must be of the same binding.

•	lhs, rhs, and answer must be of the same format (after promotion).

•	If lhs and rhs are both constant value tables (created by the Constant operator), no records will be added to the answer table.

•	If lhs and rhs are vectors or tensors, a component-wise division is performed, functioning as an inverse-scale operation).

•	If a record in rhs contains any zeros, no value will be placed in the answer table.

Expression Builder

lhs / rhs

XML Example

<call name="Divide" lhs="lhs_tab" rhs="rhs_tab"

answer="ans_tab" />

Stores the absolute value of src in answer.

Inputs

src: a value table.

Outputs

answer: a value table.

Notes

•	src and answer must be of the same binding and format.

•	If src is a constant value table (created by the Constant operator), no records will be added to the answer table.

Expression Builder

abs(src)

XML Example

Stores the reciprocal of src in answer.

Inputs

src: a value table.

Outputs

answer: a value table.

Notes

•	src and answer must be of the same binding and format.

•	If src is a constant value table (created by the Constant operator), no records will be added to the answer table.

•	If a record in src contains any zeros, no value will be placed in the answer table.

•	If src contains multiple components (a vector or tensor value), answer will contain the same number of components with each being the reciprocal of src (for example, if src is a vector, answer will contain components of 1/x, 1/y, and 1/z).
