Convert float to int in Objective-C

Question

How can I convert a float to int while rounding up to the next integer? For example, 1.00001 would go to 2 and 1.9999 would go to 2.

Answer 1

You can use following C methods to get the int values from different dataTypes.

extern float ceilf(float);
extern double ceil(double);
extern long double ceill(long double);

These functions return float, double and long double respectively. But the job of these function is to get ceil of or floor of the argument. As in http://en.wikipedia.org/wiki/Floor_and_ceiling_functions

Then you can cast the return value to desired type like.

int intVariable = (int)ceilf(floatValueToConvert);

Hope it is helpful.
