how would I change the code in order to get this answer of -1.15 and -7.85, using python3 quadratic.py 1 9 9 for example getting the answer to round up to 2 decimal places anwer comes out as The solutions are -1.1458980337503153 and -7.85410196624968 But it should be The solutions are -1.15 and -7.85 heres the code import sys def main(): if len(sys.argv) == 4: a = float(sys.argv[1]) b = float(sys.argv[2]) c = float(sys.argv[3]) d = (b ** 2) - (4 * a * c) if d < 0 or a == 0: print("There are no roots") else: root1 = (-b + d ** 0.5) / (2 * a) root2 = (-b - d ** 0.5) / (2 * a) print("The solutions are", root1, "and", root2) else: print("Please provide 3 numbers as command line arguments")
how would I change the code in order to get this answer of -1.15 and -7.85,
using python3 quadratic.py 1 9 9 for example
getting the answer to round up to 2 decimal places
anwer comes out as
- The solutions are -1.1458980337503153 and -7.85410196624968
But it should be The solutions are -1.15 and -7.85
heres the code
import sys
def main():
if len(sys.argv) == 4:
a = float(sys.argv[1])
b = float(sys.argv[2])
c = float(sys.argv[3])
d = (b ** 2) - (4 * a * c)
if d < 0 or a == 0:
print("There are no roots")
else:
root1 = (-b + d ** 0.5) / (2 * a)
root2 = (-b - d ** 0.5) / (2 * a)
print("The solutions are", root1, "and", root2)
else:
print("Please provide 3 numbers as command line arguments")
