If you define the variable as Decimal, the variable will hold a Decimal.
| c=a-b D
a is a variable of type Decimal, it will return a Decimal value,
literals are not involved here, so you don't need the "literal type
character D".
The D is part of a Literal (constant if you will) value.
2.2 is a literal
a is a variable
b is a variable
c is a variable
2.2 is a Double literal
2.2D is a Decimal literal
2.2F is a Single literal (the F stands for Float).
