Working with the random number generator

[kwelna]

It is about 20 pages long. basically it lists the functions available in pic basic and a single line about syntax. in my case it is the "Let" function. So

Here is the only reference to division:

{LET} Var = {-} Value { Op Value}

Assigns a value to a variable. the valuemay be a conmstant, the value of another variable or the result of one or more binary operations. The operations are performed strictly left to right and all operations are performed with 16-bit precision. Unary negation may only be performed on the first value.

It then lists a number of mathamatical opoerators {+, -, \, \\,....} and some boolean operators { and , or, xand, .....etc}. Nothing about truncating a number, rounding, absolute value, ...etc.

I think I have a way out, I do the division and instead of truncating and rounding off and look=king for (X = a number 1 to 5) i can test for (X <= to a number). So anything (<= to 1) is 1, (<= to 2) is 2...etc. what do yo think?

I think you're not getting it...
PBP doesn't deal with fractions. Fractions are ignored, thrown away, not present, not going to be in the final result, irrelavant...
In our little world, 10 / 3 = 3 remainder 1, or 3 1/3, or 3.333333333(and so on)

In PBP's world, 10 / 3 = 3, nothing more, nothing less.

Do you get it yet?

Hi, Kwelna

I remember there was a great discussion about random numbers ( here or in the PBP section ) ...

Oooh now I get it and the useage of the // function. OK so in essence, it always rounds down.....way easier. Sorry to be so thick
