KEY NAME DESCRIPTION
Percentage
The behavior of the % function depends upon context.
If the expression is simply a number with the % operator, the result of the
expression is the number divided by 100.
If the % operator is appended to a number which is itself to the right of
the + - × or ÷ operator, the percentage is added to, subtracted from,
multiplied by, or divided by the number to the left of the operator.
e.g.:
3 50
followed by yields a result of 4.5.
If used in a larger expression the operand must be enclosed in brackets.
e.g.:
3 50 1
results in 5.5
If is followed by any operator without a preceding closing bracket as
shown above example, a Syntax Error will result.

e.g.:
25 4
