**1 - 1, 1 -1, 1-1, 1**Hi,
I have a question regarding lexical analysis. I recently came across a
bug in our lexical analyser in phc (www.phpcompiler.org), that I am
unsure how to solve. This is the problem: our current definition for
integer constant looks something like
INT ([1-9][0-9]*)|0
In particular, note that it does not allow for an (optional) "+" or "-"
at the start of the integer. This means that the strings "1 - 1", "1
-1" and "1-1" all generate the same sequence of three tokens INT(1),
OP(-), INT(1), for which the syntax analyser generates the subtr...

**char(1) vs Number(1)**Quick check on whether char(1) is more efficient than number (1).
Basically storing a bit value of either 0 or 1. since this is a
numeric maybe its better to store this as number(1).
Did a simple test for 1million rows, the IO cost is the same but the
number of bytes is double with number(1).
This makes me think that char(1) is more efficient in storage.
any thoughts?

If you have a function generating positive random numbers

Something like:

Ah, that's different, then. Then the answer is: The result will be -2.
You have *no* guarantees about which of -1 or (1) is evaluated first,
but as they don't have side effects, you don't have to care.

I need help generating a random number between -1 and 1 with a specified mean and variance.
I'm using c=a + b*randn() with 'a' as the mean and b as the standard deviation but the problem is that since the randn function only generates a mean zero standard deviation 1 random variable then I might end up having c greater or less than 1.

**random number including 1**Hi,
random.random() will generate a random value in the range [0, 1).
Is there an easy way to generate random values in the range [0, 1]?
I.e., including 1?
I am implementing an algorithm and want to stay as true to the
original design specifications as possible though I suppose the
difference between the two max values might be minimal.
Thanks,
Esmail
ps: I'm confused by the docs for uniform():
random.uniform(a, b)
Return a random floating point number N such that a <= N <= b for a <= b
this seems to imply an inclusive range, ie. [a,b]
but this seems to contradict it...
