bcmath sometimes returns float, and sometimes round result
===

I have a variable "$newTime", which is time in seconds made by mktime(), and I want to convert it into number of days.
In this case it is over 86.400 (which is a number of seconds in a day), and I try to divide it by 86.400 to get number of days (rounded).

But sometimes I get:
Case 1: 87951 / 86400 = 1.0179513888 (1 day ago)
Case 2: 156257 / 86400 = 1.8085300925 (2 days ago)

and sometimes:
Case 1: 87986 / 86400 = 1 (Should be 1 day ago)
Case 2: 156292 / 86400 = 1 (Should be 2 days ago)

This is the code:

`$newTime = round(bcdiv($newTime, bcmul("24", bcmul("60", "60"))),0);`

When I don't use bcmath, just the regular math ($newTime / (60*60*24)), I get floating results every time...
