Is there a simple function (I solve it w a loop.. C-minded) to find the 
index of the first bigger element in an array

limit mini is first_element ,  if item < last_element
item =  -2.23
anArray = [0.0, 2.0, 5.0, 10.0, 15.0, 25.0]      first_bigger_element = 
0.0 index 0

item = 2.85
anArray = [0.0, 2.0, 5.0, 10.0, 15.0, 25.0]      first_bigger_element = 
5.0  index 2

item = 12.55
anArray = [0.0, 2.0, 5.0, 10.0, 15.0, 25.0]      first_bigger_element = 
15.0 index 4

limit maxi is last_element ,  if item > last_element
item = 36.59
anArray = [0.0, 2.0, 5.0, 10.0, 15.0, 25.0]      first_bigger_element = 
25.0 index 5

can it be writtent in just one line or a loop is unavoidable ?

thanks
