Convert double to Int, rounded down

Question

How to convert a double value to int doing the following:

Double If x = 4.97542. Convert to int x = 4.

Double If x = 4.23544. Conv         


        

Answer 1

If the double is a Double with capital D (a boxed primitive value):

Double d = 4.97542;
int i = (int) d.doubleValue();

// or directly:
int i2 = d.intValue();

If the double is already a primitive double, then you simply cast it:

double d = 4.97542;
int i = (int) d;
