First you must know if the value is a number. If it is in a column of type number you don't have to worry about that. To check if the value is an integer you can use the trunc function. This will take the decimal values off.
首先，您必须知道该值是否为数字。如果它在类型编号的列中，则不必担心。要检查该值是否为整数，您可以使用 trunc 函数。这将取消十进制值。
if trunc(value)= value then
-- we have an integer
else
-- we don't
end if;
