looking for a function or command that would only use the integer part of a number.

people with nt,



nt support is consistently excellent. i'm sure the experts with nt support won't have any problem solving this request.



oks, here is the deal; i'm trying to translate a strategy from another trading platform to nt. the only issue i have had is that in some instances i need nt to use only the integer portion from a number that can be fractional.


for example, period/2, would be an integer if period is an even number but fractional if period is an odd number.


¿what functions or commands exist in nt to keep only the integer portion of a number (that would mean rounding down no matter the value of the fractional part)?


i have noticed the strategy builder sometimes uses something like converttoint.32, but i couldn't find any references to this command. ¿does it round up for values above .5 and round down for values below as is usual? i haven't been able to determine how this command works, therefore i decided to ask for support.



very well, thanks, regards,

Lots of choices.

Btw, this is a basic C# programming question, nothing to do with NinjaTrader.

For all things C# programming, StackOverFlow.com is your friend.

I would probably just use the typecast example.

If your number is stored in a double variable, like this,

double num = 13.67832;

then this code,

int newnum = (int)num;

converts the double value of num to integer, completely dropping (not rounding, dropping) the decimal portion of num.

Again, a nice explanation from StackOverFlow.com,

https://stackoverflow.com/questions/13292148/casting-a-double-as-an-int-does-it-round-or-just-strip-digits

How can you find these answers for yourself?

Try googling with searches like,

C# drop fraction
C# typecast int to double

Always prefix your google query with 'C#' and you'll get lots of terrific answers, usually at StackOverFlow.com.

thanks, bltdavid and Paul H.



i continued to research into this matter and learned that the Convert.ToInt32 function is definitely not what i have been looking for. microsoft defines it as:


Returns
Int32

value, rounded to the nearest 32-bit signed integer. If value is halfway between two whole numbers, the even number is returned; that is, 4.5 is converted to 4, and 5.5 is converted to 6.


in the end, i just placed an (int) command before each instance where any calculation is done to the value for period and this worked perfectly, for example: (int)(Period / 2).



thanks again, regards.
