Trying to implement Newton's method to find roots in polynomials using Horner's method.
n=len(a)-1
print("k\t a\t x\t px")
for k in range (0, iterMax):
b=a[0]
c=b
for i in range (n-1,1):
b=a[i]+(b*x)
c=x*c+b
b=b*x+a[n]
if x in range of (-epsilon, epsilon)
print ("raiz encontrada")
on the line
if x in range of (epsilon, epsilon)
The compiler warns that "'float' object can not be interpreted as an integer"
It makes no sense for you to make a fork with float numbers, so you should rent it.
Use the round method.
Example:
round(3.2)
Output:
3
If you really need to work with float numbers in a range, use the While loop as long as the condition is not found.
But in your case, you're just asking if a number is in a domain, I suggest you do it here:
n=len(a)-1
print("k\t a\t x\t px")
for k in range (0, iterMax):
b=a[0]
c=b
for i in range (n-1,1):
b=a[i]+(b*x)
c=x*c+b
b=b*x+a[n]
if (x>=(-epsilon) and x<=(epsilon)): # Aqui foi feita a mudança.
print ("raiz encontrada")
