separating the integer part of a number from the fractional part

I have columns of decimal numbers (representing fraction day of year). I need to separate the fractional part of the number (to the right of the radix point) from the integer part. For example, if the number were '207.65' Id like to make a separate column which contained only '65' or even better, '0.65.' What I am trying to do is separate day from night. Any ideas?? Thanks. -JPG
207.65 %%1
[1] 0.65
207.65 - trunc(207.65)
[1] 0.65
207.65 - floor(207.65)
[1] 0.65 Notice differences for negative numbers though:
-207.65 %%1
[1] 0.35
-207.65 - trunc(-207.65)
[1] -0.65
-207.65 - floor(-207.65)
[1] 0.35
