c# - When formatting floats in DataGridView to a certain decimal, cannot copy full number -

-

i'm creating windows form application, more or less acting interface sql db our users. want format floats 1 or 2 decimal places when @ form, want have ability copy datagridview out excel full float if desire.

for example, if i'm formatting rows percent 1 decimal place i'll use

datagridview1.rows[i].defaultcellstyle.format = "p1";

this looks great in form, when copy datagridview clipboard, copies 1 decimal place, if float datatable i'm using source has more decimal places.

i'm having trouble figuring out how copy unformatted data clipboard. i've considered making copy button accesses invisible datagridview unformatted, i'd users able ctrl-c visible, formatted datagridview.

any ideas? letting me know i'm out of luck help, i'll give on ctrl-c functionality , create separate copy function. thanks.

it impossible allow users copy different being displayed (1-decimal values). workaround want might enabling 2 different "modes" show information in cells: short , long format. , adding user-friendly way switch between both modes; example: pressing "enter" in cell. sample code:

private void datagridview1_keydown(object sender, system.windows.forms.keyeventargs e) {     if (e.keycode == keys.enter)     {         if (shortmode)         {             datagridview1.rows[currow].defaultcellstyle.format = ""; //number decimals             shortmode = false;         }         else         {             datagridview1.rows[currow].defaultcellstyle.format = "p1"; //number percentage 1 decimal             shortmode = true;         }     } }

where shortmode boolean variable declared globally , currow row want change.

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
