[SOLVED] How do I shorten a number?

[kjtocool]

Can I use substr() on numerical float variables?

 

For example, if I have 9.33333333333333333333333333333333333333 repeating, and I want to only keep the first 5 characters (including decimal point), how do I go about doing so?

Do you want any rounding?

[kjtocool]

That's a good question.

 

I suppose yes I do.

 

Example:

 

9.126709098

 

I would want:

 

9.127

Well then, I'd say you should round() then

 

echo round(9.126709098, 3);

Yep, that's exactly what I was looking for.  Thanks.

I dont think that will give you just five digits, it will just give you 3 after the decimal.  So you'll still get 123123123.123
