number conversion

[Former Member]

hi,

1.I have a doubt.if i do arithmetic operation on two floating point numbers(data type F) and assign it to a packed number(P) how will it affect the final result.

2.Another question how can i convert a negative packed number into positive packed number.

Please answer.

thanks and regards,

Mahesh

a) you will have rounding errors.

b) var = - var.

INTLEN tells us the number of bytes used by this field; DECIMALS the number of decimals for packed and floating point numbers.

reward point if helpful.

HI,

1)we will get round off errors.

2)here num is pack type variable.

num = abs( num ).

<b>example</b>

DATA:num TYPE p value '-1.23' DECIMALS 2.

write:/ num.

num = abs( num ).

write:/ num.

rgds,
