As is known to all, the definition of Fibonacci Numbers is:
f(1)=1
f(2)=1
f(n)=f(n-1)+f(n-2) (n>=3)
Now Sempr found another Numbers, he named it "Sibonacci Numbers", the definition is below:
f(x)=0 (x<0)
f(x)=1 (0<=x<1)
f(x)=f(x-1)+f(x-3.14) (x>=1)
Your work is to tell me the result of f(x), is the answer is too large, divide it by 1000000007 and give me the remainder.
Be careful the number x can be an integer or not.
