Join 2 integers (integral and decimal part) to a double in C# -

-

consider following code:

int integralpart = 123; int decimalpart = 12345; // double desireddouble = 123.12345;

i create double 2 ints, shown in example.

i know can use double.parse(integralpart.tostring() + "." + decimalpart.tostring()), getting exceptions if application isn't using english default language.

from wording alone, i'd suggest wanted use decimals:

int integralpart = 123; int decimalpart = 12345;  decimal result = decimalpart; while (result>=1m) result/=10m; // caveat: see below  result+=integralpart;

oops. , there big ambiguity problem others have mentioned. likely, you'd need replace while fixed scale:

result = integralpart + decimalpart / 1000000m; // fixed scale factor

-
i using tfs's team explorer manage visual studio projects. recently, i've created new java project (not in visual studio) manually added tfs using source control control explorer in visual studio. after added java project tfs, made changes , bug fixes. then, went visual studio , opened source control explorer check in changes, tfs thinks no changes made. it seems needed check out project before making changes. guess erroneously expected tfs track automatically, okay. so, using source control explorer in tfs, checked out project, , tried check in pending changes. when tried check in, got following message: all of changes either unmodified files or locks. changes have been undone server. is there way convince server indeed project has changed? how can check in changes have made? thank help.
