Fortran code question: what does numb(1)=1. mean ?

[cwjcwjcwj]

Pls help on Fortran

do i=1,33
numb(i)=0.
cum_numb(i)=0.
end do

numb(1)=1.
do i=2,n+1
numb(i)=numb(i-1)*((n-i+2)/(i-1))
end do

I have a code from fortran as above. Just wondering, what is numb(1)=1. means?I mean what is the '.' in fortran mean?Is it meaningless?If I convert to Matlab,is it as following numb(1)=1;?Thanks

0. , 1. in the expressions would mean real number representation.
num(i) = 1. <=> num(i) = 1.0
It means the array num() contains real numbers. In case o integers you would see:
numi(i) = 0
