The Math library contains the following Power operators:
Stores the square root 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 src is a real value table and contains any negative values, no value will be placed in the answer table. |
|
Expression Builder
|
sqrt(src)
|
XML Example
|
<call name="SquareRoot" src="src_tab" answer="ans_tab" />
|
|
Stores src raised to the power of exp in answer.
Inputs
|
src: a value table.
exp: the exponent.
|
Outputs
|
answer: a value table.
|
Notes
|
• | src and answer must be of the same binding and format. |
• | If a value in src is large enough to cause a floating-point overflow, no record will be added to answer. |
• | If src is a constant value table (created by the Constant operator), no records will be added to the answer table. |
|
Expression Builder
|
src ^ exp
|
XML Example
|
<call name="Power" src="src_tab" exp="3" answer="ans_tab" />
|
|
Stores the number e raised to the power 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 a value in src is large enough to cause a floating-point overflow, no record will be added to answer. |
• | If src is a constant value table (created by the Constant operator), no records will be added to the answer table. |
|
Expression Builder
|
exp(src)
|
XML Example
|
<call name="Exponent" src="src_tab" answer="ans_tab" />
|
|
Stores the log of src in answer.
Inputs
|
src: a value table.
base: e or 10 (default is 10).
|
Outputs
|
answer: a value table.
|
Notes
|
• | src and answer must be of the same binding and format. |
• | If a record in src contains any zeros, no value will be placed in the answer table. |
• | If src is a constant value table (created by the Constant operator), no records will be added to the answer table. |
|

log(src,base)
|
XML Example
|
<call name="Log" src="src_tab" base="e" answer="ans_tab" />
