I can see from experimenting in PD that % doesn't want to behave the  
same for decimal numbers.
i.e. if I set % to 1 and increment (x[n] + 1/100) % 1
nothing happens
so I need some sort of fmod to deal with the fact that now the values  
I am generating range from 0 to 1 in 0.01 increments.

could you expand on

fractional part of f = f - int(f)

i.e. because I need to limit things to 1 the % 1 is not going to work  
so I need a different function that will do the same thing for  
decimals limited to 1.

how would I approach that in PD?


Thanks for the input
