c# - Increasing the value by 1 if it has decimal place? -

my scenario if

47/15= 3.13333 

i want convert 4, if result has decimal want increase result 1, right doing like

        float res = ((float)(62-15) / 15);         if (res.tostring().contains("."))         {              string digit=res.tostring().substring(0, res.tostring().indexof('.'));              int incrementdigit=convert.toint16(k) + 1;           } 

i want know there shortcut way or built in function in c# can fast without implementing string functions.

thanks lot.

do mean want perform integer division, rounding up? suspect want:

public static int dividebyfifteenroundingup(int value) {     return (value + 14) / 15; } 

this avoids using floating point arithmetic @ - allows value isn't exact multiple of 15 rounded up, due way integer arithmetic truncates towards zero.

note not work negative input - example, if passed in -15 return 0. fix with:

public static int dividebyfifteenroundingup(int value) {     return value < 0 ? value / 15 : (value + 14) / 15; }
