40.3. Mathematical function
Extended functionality of the mathematical functions with use of a variable
<{5} Mathematical function> enables carrying out an optional operation on
numbers and variables available on the list. The basic available mathematical
functions are:
• Adding (+)
• Subtracting (-)
• Multiplying (*)
• Dividing (/)
The additional functionality provides using in the calculation the existing
variables, thus enabling acquiring mass from a specified weighing platform,
and its processing in a desired way.
An example:
{5: ([43:1] + [43:2]) / 2}
The above application of a variable <{43} Platform mass> causes acquiring
mass from a weighing platform determined in the formatter (:1 and :2), and
their dividing by 2 which enables taking the average mass from both weighing
platforms. Use of the brackets enables carrying out the operation in an
appropriate sequence and in accordance with basic matjematical principles.
Notice:
Variables in the structure of the mathematical operations are noted insquare
brackets [ ] and not as previously in { } brackets.
Additionally, a operator can use the advanced functions enabling extended
means of data modification. The advanced functions are used in a form of text
marker and arguments in brackets:
• round (numeric value, rounding precision (number)) - rounding
• abs (numeric value) – absolute value
• sin (numeric value) - sine
• cos (numeric value) - cosine
• tan (numeric value) - tangent
• sqrt (numeric value) - radical
• pow (numeric value, power base (number)) - power
• log (numeric value) – logarithm
• log10 (numeric value) – logarithm base 10
