Integer expression

Question

int (5*2.4)
=12

int (5)*(2.4)
=10

Why this expression gives different results?

Answer 1

tried this two on Ubuntu, first is int 12, second 12 in float.

Answer 2

2.4 in int is 2, then 5*2=10.

Answer 3

int(2.4) chops off the ".4"

Answer 4

Because int(5*2.4) converts 12.0 to an integer,
int(5)*(2.4) only converts 5 to int. THEN multiply it by 2.4, and gives you 12.0 as a float

Answer 5

sorry guys
I mean, the second expression is:
int (5)* int (2.4)
=10
Why 10 and not 12
