Re: lingo-l Getting separate parts of a number
A more traditional way, just using abs and some math, gives you: intPart =integer(abs(myFloat) - 0.5) * (-1 + (((myFloat + abs(myFloat)) / (myFloat * 2))*2)) floatPart =abs(myFloat) - abs(intPart) It's the same as my original posting, but abs'ing everything to get the numbers, and that second part of the intPart equation is to restore the sign to its proper place. - Tab [To remove yourself from this list, or to change to digest mode, go to http://www.penworks.com/lingo-l.cgi To post messages to the list, email [EMAIL PROTECTED] (Problems, email [EMAIL PROTECTED]).

lingo-l Getting separate parts of a number
Hi, I have a floating point number, e.g. 45.6200, and I want to be able to store the whole number part and the fraction part separately, so that I can increment an integer value and keep the remainder (the fraction part) to be added on to a later increment value.
