Numeric Variable Declaration Statements. Each numeric variable
declaration statement explicitly declares one or more numeric scalar or
array variables. The type of the variables depends on the statement.
Table 3-11 lists the numeric variable types, the number of bits used to
store the value, the range of each type, the precision of each type, and
the declaration statement that declares variables of that type. HP
Business BASIC/XL accepts the character "D" as well as "E" to indicate
scientific notation.
