I have successfully written a float number into a sybase system - that I can display correctly with isql.
But when reading with php I got back 0 oder some strange numbers as 6.784567 instead of teh correct float number.

I found that the wrong float results happen with float(8) but NOT with float(16) !!!

Can you reproduce this error with PHP 4.1.1?

I have the same error with PHP4.1.1.
Even though I use float(16) instead of float(8),
or use decimal(15,5), I got the wrong display when fetch a float/decimal/double field.

I have verified the same problem.

In a table stored on a mssql 6.5 server, accessed via FreeTDS (both release 0.53 and 0.60.rc3) I have a column which is a float(24).

I can confirm that accessing that table works fine both from the tsql utility supplied with freetds and from sqsh.

That column's fields are however zeroed out when I access from inside PHP. This is both on 4.1.1 and 4.2.2.
The host operating system is Redhat 7.1.

I Experienced the same problem, but found a workaround.
If I enclose the offending column by 

CAST(clumn AS DECIMAL) 

I get the correct result.
