<div class="section"><div class="p">The format of the keyword is: <pre>FLTPCN(*SINGLE | *DOUBLE)</pre>

where

the *SINGLE parameter is single precision and the *DOUBLE parameter is double

precision.</div>
|

|
|
<p>This keyword is valid for floating-point fields only (data
|

|
type F).</p>
|
||
|
|
<p>A single-precision field can be up to 9 digits. A double-precision
|
||
|
|
field can be up to 17 digits. If you specify a field length greater than
|
||
|
|
9 (single precision) or 17 (double precision), an error message is issued
|
||
|
|
and the file is not created. ICF supports a floating-point accuracy of 7 digits
|
||
|
|
for single precision and 15 digits for double precision.</p>
