VectorPro README file:
VectorPro is provided as "shareware".
Please see the file VPORDER.TXT for registration information.
Vector Numerics, Inc. is a member of the Asociation of Shareware
Professionals.
This is the small shareware version. It contains the documentation files
and the C version of the VectorPro library for the medium memory model.
A large shareware version is available from Vector Numerics, Inc. for
the benefit of those who would like to see the entire product for
evaluation. See VPORDER.TXT for details.
Known Problems:
1. Some test programs using Phar Lap have bombed with a General
Protection Fault while running as a DOS session under Windows,
but work fine under pure MS-DOS. I am writing this off as
flakiness in Windows or the Phar Lap - Windows interface for now.
I am most interested in any new information relevant to this.
2. The Pentium Bug: There is no way a product of this nature can avoid
doing the occasional floating point division, or control the range
of input values it is given. If you are using one of the flawed
Pentiums, add the line SET NO87=NO to your AUTOEXEC.BAT file. This
will cause the Microsoft floating point emulator to run even though
it can find '87 hardware on your system. It will also cause quite
a slowdown, but at least you can have confidence in your results
until you get a replacement chip.
Version 1.1:
The following changes have been made from version 1.00 to 1.1:
1. cpx_ln has been modified to always produce a result with imaginary
portion from -pi to pi, instead of 0 to 2pi.
2. cpx_cpx_power's handling of the imaginary portion of the exponent
has been corrected.
3. Some 87 hardware running around sometimes stores a negative zero.
All routines that were thrown off by this have been adjusted.
4. The library distributed as the small shareware version has been
changed to be the medium model C version. This was done because
Microsoft's AppWizard generates only Medium and Large model code.
The HVECPROA.LIB or HVECPRO7.LIB may be used if huge arrays are used.
