Why 120*1000 != 120,000?

[J-M-L]

Using UL, like @DrDiettrich says, on either (or both) the 120 or 1000 forces the compiler to use unsigned long for the answer

as cooldown is an int, it would not work to do

int cooldown = 1000ul;
long timerTmp = 120 * cooldown;

the maths would still be conducted as int

you need to do

int cooldown = 1000;
long timerTmp = 120ul * cooldown; // ul to force calculation using long

or store cooldown as a long

long cooldown = 1000;
long timerTmp = 120 * cooldown; // cooldown being a long, the math is done using long
