rounding on some decimal numbers

```
What steps will reproduce the problem?
1. When you have to read a certain excel file, the function _getCellDetails
format a decimal number and the format is like 0.0000 , the variable of format
is read or has a numeric type; changing the format of the variable to string
fixes de rounding resulting number.

What is the expected output? What do you see instead?
a decimal number , rounded number
example; expected 6.96000 , see instead: 7.77777

Please provide any additional information below.
I fixex, in this way:
version 2.21
function _getCellDetails
after line: 1633; I added this:
if($format==0.00000 ){
$format="0.00000";
}

```

Inspect the attached excel_reader2.php around _getCellDetails and line 1633, then reproduce the issue with TablaDeCotizaciones_bnb_2012_04_18.xls. Compare the parsed format and resulting decimal value with the reported expected output. Done means the affected decimal formatting no longer produces the incorrect rounded number.
