Math.round(4.7)

How do I round to the lower number? (4 in this case)

Dizzutch · Mar 10th, 2005, 3:58 PM

integer division by 1..

there might be a floor function, but i don't know JavaScript that well.

Navid · Mar 11th, 2005, 11:02 AM

you mean 4/1?

But that would still leave me with a decimal.

Dizzutch · Mar 11th, 2005, 12:35 PM

not if you do integer division, but i don't know if you can do that in JS. IN C at least
float a = 4.3;
int b = 1;
int c = a / b;
printf("%d\n", c); // prints 4

I believe num.floor() works as well.

Navid · Mar 11th, 2005, 4:19 PM

you probably ment Math.floor()

it worked, thanks
