Using Math Functions with Lists
Using Math Functions with Lists
When a math function (see Chapter 2: Math Operations) is
applied to a list, it is calculated for every element in the list.
Therefore, the function must be valid for every element in the
list.
You cannot perform a mathematical function on two lists of
You cannot perform a mathematical function on two lists of
different sizes. For example,
{1,2,3}+{4,5,6,7}
results in an error.
Mathematical rules always apply; for example,
1
P
{0,1,2}
results
in an error because 1 cannot be divided by 0.
