I've tried a few ways of coding the second part of this problem, all of which execute correctly, but none of them allow me to successfully submit and continue.
I get the error 'Oops, try again. Your second call to round() should print a floating point number with exactly 3 digits after the decimal.
Can anyone help?
// Try rounding a floating point number to an integer
// and print it to the screen
$num = 1.68456;
$rounded = round($num);
print round(1.71254, 3);
