Examples of FIXED Numeric Constants

Storage Format

The system stores a FIXED number in binary notation. When the system stores a

FIXED number, it scales the constant as dictated by the declaration or expression.

Scaling means the system multiplies or divides the constant by powers of 10 to move

the decimal.

For more information on scaling of FIXED values in expressions, see Section 4,

Expressions.

For more information on scaling of FIXED values in declarations, see Section 6, Simple

Variables.
