Q]] The correct length of bytes , which a type F field can have is 8 , --this is also the valiud length. Then how is it possible for these fields to hold values as large as

[ (10)*(-307) TO (10)* 308]

Q]],Why is it that the syntax

NUMBER TYPE RF VALUE ‘4.3’

Gives an output

4.30000000000000 E +00

good

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.

Using I and F fields for calculations is quicker than using P fields. 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 ..

Type F field will use 8 bytes . But is is not a Character field which takes one byte per character.

Type F fields will store the Value in Exponent and Mantissa Format. So that it can accommodate a large range of Values.

Hope u got it.
