Bug description:Untrue statement about microtime() precision
Description:
------------
---
From manual page: https://php.net/function.microtime
---
It states:
"If as_float is set to true, then microtime() returns a float, which
represents the current time in seconds since the Unix epoch accurate to
the nearest microsecond."
That's not true. The value returned as float is not accurate to the
nearest microsecond. Now I guess that's obvious if you know what the
precision of a float is, but if I read a sentence that says "accurate to
the nearest microsecond", I'm not going to do maths, I'll assume that
who wrote the sentence already did that for me, so if they say "accurate
to the nearest microsecond" I'll assume they figured out that the
typical precision of a float is enough to give you a 1-microsecond
precision on such a number.
