How to seperate fractional and decimal part in a real number

Hi, Please help me in seperating fractional and decimal part in a real number. For example: If the value is '1.23', I need to seperate decimal part '1' and 'fractional part '0.23'.

Thanks and regards, soumya..

Are you talking of numbers or strings? The quotes in '1.23' might be misleading.

Jan Its my pet peeve when a poster poses a question and it is responded to with another unnecessary question. Yes, in Matlab syntax, '0.23' indicates a string, but it is really obvious that he meant 0.23. I guess my wish to responders is simply, 'Just answer the question already' !!

Answer 1

number=1.23;
integ=floor(number);
fract=number-integ;

That fails on negative numbers. For negative numbers, you need fract=number-ceil(number)

Answer 2

i think the better way is to use: number = 1.23; integ = fix(number); fract = abs(number - integ);

it works for both negative and positive values.
