Bisection or Regula Falsi Method

[abrowaqas]

The method of false position or in Bisection method. can we put initial values as the integer values or it is necessary that the initial values must be whole numbers?

E.g suppose i have question . x(3)-x-11=0 where x(3) is x raised cube

for initial values a and b. if i put a=2.3 and b= 2.4 . for 'a' function give -ve value and for 'b' function give +ve value.. is that supposition of 'a' and 'b' is correct . or i must have to put whole number. i-e a=2 and b=3 . and then start respective iterations of false position or bisection.

It is perfectly acceptable to use decimal numbers as your starting values!
