Using the 162Bug Debugger

This format provides a convenient way to enter and display a 
floating point decimal number. Internally, the number is assembled 
into a packed decimal number and then converted into a number of 
the specified data type. 

Entering data in this format requires the following fields: 

❏

An optional sign bit (+ or -).

❏

One decimal digit followed by a decimal point.

❏

Up to 17 decimal digits (at least one must be entered).

❏

An optional Exponent field that consists of:

РAn optional underscore.

РThe Exponent field identifier, letter ÒEÓ.

РAn optional Exponent sign (+, -).

РFrom 1 to 3 decimal digits.
