Using the 187Bug Debugger

Scientiﬁc Notation

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 Þeld that consists of:

An optional underscore.

The Exponent Þeld identiÞer, letter ÒEÓ.

An optional Exponent sign (+, -).

From 1 to 3 decimal digits.

For more information about the floating point SFU, refer to the MC88100 RISC Microprocessor User's Manual.
