With Visual Fortran for Win inside Microsoft Visual Studio 2008: Visual Studio datatip for single variable works, but VS sends error message and
doesn't display for datatip of an expression, particularly using "**"
for exponential or when expression includes more than one type of operator. This worked correctly with Visual Studio 2005.
Is there a patch or comipler option that addresses this?
example:
at a break during debug when all variables are defined and have values, part of the equation is selected with the mouse and then hovered over to get current value. In the C++ code this works fine. You can even get an answer for a non-parenthesied expression that, within context of the full equation, disobeys order of operations
test1 =2;
test = 1.139E-9*test1*1.75;
(with the E signalling decimal location)
In C++, a datatip value is given for 9*test1 (even though that is an incorrect thing to ask in context of the whole equation), or for test1*1.75, or1.139E-9 or 1.139E-9*test1*1.75
Written in Fortran and compiled into the C++ project, 9*test1 works but no other no part of the A= equation can be looked at using datatips including test1*1.75, or1.139E-9 or 1.139E-9*test1*1.75. Instead VS does nothing or asks to send an error report.
Error reports are sent particularly when operations are mixed. The data tip seems to work most often for * and for / , and is worse for + - or **
