C problem for rounding a decimal value

8 New Member
i have written a code which yields a decimal value for example 7.23, but i need the value greater than this number i.e the number integer 8.
Can anyone suggest a way to do this please?
what should I use?

If you have the float number a, just write: (int)a+1 and you'll have the rounded number you want(and use the condition that a>(int)a)

Don't do that: an int isn't large enough to hold the integer part of any double value.
Better use the ceil() function (in <math.h>).

kind regards,
