Is there something wrong with this function?

It is supposed to figure out if the number is whole or not. if not it rounds down, if it is it squares.

function [remainder]=data_modifier(data1)
remainder=rem(data1,1)
if remainder==0
    sqrt(data1)
else
    floor(data1)
end
end

No error. Why?

However, change your output of function, i guess remainder is not the output you wanted.

No it’s not correct if the input is float ,it fails

[madhan ravi]

function [result]=data_modifier(data1)

   if isfloat(data1)==1
  sqrt(data1)
   else 
  floor(data1)
   end 
  end

[madhan ravi]

The above shows if the number is a decimal it takes square root if not it rounds

Anytime, accept the answer so that people know problem is solved

Hi jonathan,

change your function output to

function ans = data_modifier(data1)

[madhan ravi]

never name an output as ans because it will contradict with the mat labs inbuilt variable named as ans
