oci_field_precision
(PHP 5, PHP 7, PHP 8, PECL OCI8 >= 1.1.0)
oci_field_precision — 返回字段精度
说明
oci_field_precision(resource
$statement
, int $field
): int
返回索引为 field
(从 1 开始)的字段的精度。
对于 FLOAT 字段,精度为非零值且范围为 -127。如果精度为 0,则字段为 NUMBER。其它类型为 NUMBER(precision, scale)。
注意:
在 PHP 5.0.0 之前的版本必须使用 ocicolumnprecision() 替代本函数。该函数名仍然可用,为向下兼容作为 oci_field_precision() 的别名。不过其已被废弃,不推荐使用。

I did not test well before posting previous code. This if statement works and the other does not.
if( ocicolumnscale($R, $i ) != 129 )
{
$int_decimal = ocicolumnscale($R, $i );
$int_length = ocicolumnprecision($R, $i) - $int_decimal;
}

I've found that when using ocicolumnprecision or oci_field_precision it will not show you the decimal places if you are are reading from tables with decimals. You can use ocicolumnscale or oci_field_scale to find the decimal.
if( ocicolumnscale($R, $i ) > 0 )
{
$int_decimal = ocicolumnscale($R, $i );
$int_length = ocicolumnprecision($R, $i) - $int_decimal;
}
