c# - cannot implicitly convert type 'float' to 'int' -

when try run following code gives error " cannot implicitly convert type 'float' 'int' ".

i have done lot of searches, , sadly wasn't able find such error.

int sum1, cols, rows;  float h, twoends, x;  sum1 = (h - ((cols) * x) + twoends)) / (cols + 1); 

the errors puts clear

cannot implicitly convert type 'float' 'int'

so have float result can't converted implictly sum1 of type int. try converting/casting explicitly:

 sum1 = (int) ((h - ((cols) * x) + twoends)) / (cols + 1));
