min ( number arg1, number arg2 [, ...])
number
min ( array numbers)
min() returns the numerically lowest of the
parameter values.
In the first variant, you need at least two parameters
and min() returns the lowest of these values.
You can compare an unlimited number of values.
In the second variant, min()
returns the lowest value in numbers.
If one or more of the values is a float, all the values
will be
treated as floats, and a float is returned. If none of the
values is a float, all of them will be treated as integers,
and an integer is returned.
