Hi Corona688...

This edge case works on my version...
I have limited my decimal point to 9 decimal places BUT note the non-zero digits start at the 10th decimal place:
Code:
Last login: Wed Dec 12 06:48:08 on console
AMIGA:amiga~> cd Desktop/Code/Shell
AMIGA:amiga~/Desktop/Code/Shell> ./calc .000000000123 + .0000000007
+0.000000001
AMIGA:amiga~/Desktop/Code/Shell> ./calc .000000000923 + .000000000739
+0.000000002
AMIGA:amiga~/Desktop/Code/Shell> ./calc .000000000123 + .000000000123
+0.000000000
AMIGA:amiga~/Desktop/Code/Shell> _

I have certainly discovered that it is more difficult than I expected. There is at least one division edge case that is not straightforwards.
As I stated before python 2.x or 3.x was my friend here...
But yours in 'bash' gives...
I have changed 'AA' and 'BB' to:
Code:
AA=0.000945
BB=0.000789

There are other edge cases.
Ignoring the divide case as that is an edge case in itself and is different from the one mentioned above.
Code:

AMIGA:amiga~> cd Desktop/Code/Shell
AMIGA:amiga~/Desktop/Code/Shell> ./FPMATH_C688.sh
0.000945 * 0.000789 = 0.000
./FPMATH_C688.sh: line 54: (A*MOD)/B : division by 0 (error token is " ")
0.000945 / 0.000789 = 
0.000789 - 0.000945 = 0.000
0.000945 - 0.000789 = 0.000
0.000945 + 0.000789 = 0.000
AMIGA:amiga~/Desktop/Code/Shell> _

This is getting more difficult by the version.

Hi C688...
Your mandlebrot probably won't work on the AMIGA, period, as there is no bash for it, only ksh88.
Nevertheless it looks cool.
Off to try it out on this machine...
OSX 10.14.1, default bash terminal.
I'll be back to let you know...

CPANPLUS::Shell(3pm)					 Perl Programmers Reference Guide				      CPANPLUS::Shell(3pm)

NAME

       CPANPLUS::Shell - base class for CPANPLUS shells

SYNOPSIS

	   use CPANPLUS::Shell; 	    # load the shell indicated by your
					    # config -- defaults to
					    # CPANPLUS::Shell::Default

	   use CPANPLUS::Shell qw[Classic]  # load CPANPLUS::Shell::Classic;

	   my $ui      = CPANPLUS::Shell->new();
	   my $name    = $ui->which;	    # Find out what shell you loaded

	   $ui->shell;			    # run the ui shell

DESCRIPTION

       This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "CPANPLUS"
       shell.

       Just about all the functionality is provided by the shell that you have loaded, and not by this class (which merely functions as a generic
       loading class), so please consult the documentation of your shell of choice.

       Please report bugs or other issues to <bug-cpanplus@rt.cpan.org<gt>.
