There's different ceiling functions, depending on what you want to do:

double ceil(double x);
float ceil(float x); [C++ only]
long double ceil(long double x); [C++ only]
float ceilf(float x); [required with C99]
long double ceill(long double x); [required with C99]

Code:

#include<iostream>

float Round(float number)
{
	float f_temp = number * 10.0;
	int i_decimal = (int) f_temp % 10;
	if( i_decimal >= 5) 
	{
		i_decimal = (int) number +1;
	}else
	{
		i_decimal = (int) number;
	}
	return i_decimal;
}

int main()
{

	std::cout << Round(7.5);
	return 0;
}
