Performs a calculation on the value of variable a and saves the result back to the variable. If d is "true", the type of the variable will be checked and the mapping will be finished with an error if the type is not numerical.
In the case of a division, e specifies the number of digits the result should be rounded to. If nothing or "0" is specified, the result will be rounded to the number of the dividend's digits.
The result of the function is the result of the calculation.
