Is there a way to print the actual value instead of exponential value?
>>> val=0.00004
>>> print(str(val))
4e-05

As posted in here: How do I suppress scientific notation in Python?
print('{0:f}'.format(val))

Try this,
print('{:f}'.format(val))

I am working on some floating point addition in Python, i found this difference, changing the order of addition changes the value.
v1=2.7776548790102065

v3=-2.5635999386901154

v8=-7.074990233473147
v9=12.624973219138516
print(v1+v2+v3+v4+v5+v6+v7+v8+v9) # 11.239886986191486
print(v1+v4+v7+v2+v5+v8+v3+v6+v9) # 11.239886986191484

As you would do it with integer powers:
x ** (2 / 3)
Try this code here:
Also, you can initialize x
x=3
x**(2/3)

How to make NumPy print trailing 0s? [duplicate]

Pretty-print a NumPy array without scientific notation and with given precision
(14 answers)
Closed 6 years ago.
When printing arrays, Numpy replaces trailing 0s with s, e.g.
[-0.678231 -0.618304 -0.6077 0.014845]
How can I fix this and make it print the 0s?
You can use numpy's set_printoptions with a custom formatter to set the precision and exact format of the output; for your case,
np.set_printoptions(formatter={'float': '{: 0.3f}'.format})
should do the trick.
