Mathematical and Functional Expressions
For manipulation of data, the LEGEND-MC provides the use of the following mathematical operators:
The numeric range for addition, subtraction and multiplication operations is +/-2,147,483,647.9999. The
precision for division is 1/65,000.
Mathematical operations are executed from left to right. Parentheses can be used and nested four deep.
Calculations within a parentheses have precedence.

SPEED=7.5*V1/2
The variable, SPEED, is equal to 7.5 multiplied by V1 and
divided by 2
COUNT=COUNT+2
The variable, COUNT, is equal to the current value plus 2.
RESULT=_TPX-
(@COS[45]*40)
Puts the position of X - 28.28 in RESULT. 40 * cosine of
45
° is 28.28
TEMP=@IN[1]&@IN[2]
TEMP is equal to 1 only if Input 1 and Input 2 are high
