Hi friends,

what is the different of the types P and F.

Hi,

Both these types are used for decimal numbers. In the type P you could specify the lenght of the decimal fields and in F there is a default setting for the decimal point.

Thanks..

Hi,

Packed numbers - type P

Type P data allows digits after the decimal point. The number of decimal places is generic, and is determined in the program. The value range of type P data depends on its size and the number of digits after the decimal point. The valid size can be any value from 1 to 16 bytes. Two decimal digits are packed into one byte, while the last byte contains one digit and the sign. Up to 14 digits are allowed after the decimal point. The initial value is zero. When working with type P data, it is a good idea to set the program attribute Fixed point arithmetic.Otherwise, type P numbers are treated as integers.

You can use type P data for such values as distances, weights, amounts of money, and so on.

Floating point numbers - type F

The value range of type F numbers is 1x10*-307 to 1x10*308 for positive and negative numbers, including 0 (zero). The accuracy range is approximately 15 decimals, depending on the floating point arithmetic of the hardware platform. Since type F data is internally converted to a binary system, rounding errors can occur. Although the ABAP processor tries to minimize these effects, you should not use type F data if high accuracy is required. Instead, use type P data.

You use type F fields when you need to cope with very large value ranges and rounding errors are not critical.

<b>Using I and F fields for calculations is quicker than using P fields</b>. Arithmetic operations using I and F fields are very similar to the actual machine code operations, while P fields require more support from the software. Nevertheless, you have to use type P data to meet accuracy or value range requirements.

Hi,

<b>Data Type Initial Field Length Valid Field Length Initial Value Meaning</b>

F 8 8 0 Floating point number

P 8 1 - 16 0 Packed number

You can use type P data for such values as distances, weights, amounts of money, and so on.

You use type F fields when you need to cope with very large value ranges and rounding errors are not critical.

Reward if useful!

both p and f are numeric types

Data types C, N, P, and X are generic. When you use a generic type to define a local data type in a program or a data objet, you must specify the field length and, in the case of type P, the number of decimal places.
