Determining the appropriate range for the given number.

I want to know, if I have a number such as 1.5 and I have 120 equal segments of number-line from 0.00 to 6.00 how can I determine in which segment this number (in this case 1.5) can be placed. I know I can use 'if-elseif' but for checking 120 case with 'if-elseif' seems very difficult. Is there any other way to do it?

x = 1:120 ; 
y = linspace(0.,6,120) ;
xi = 1.5 ;

yi = floor(interp1(y,x,xi)) ; 

fprintf('%f should be placed between %f and %f\n',xi,y(yi),y(yi+1))

OR:

x = linspace(0.,6,120) ;
xi = 1.5 ;

[val,idx] = min(abs(x-xi)) ;

fprintf('%f should be placed between %f and %f\n',xi,x(idx-1),x(idx))

OR:

x = linspace(0.,6,120) ;
xi = 1.5 ;

idx = knnsearch(x',xi) ;

fprintf('%f should be placed between %f and %f\n',xi,x(idx-1),x(idx))
