equal method adding an extra dimension to the variable

[Vulinux]

Hello,

I had a question about the equal method. Why does equal method add an extra dimension to the variable calling it? I provided a simple piece of code that demonstrates this. If I choose to set the value with the equal method, scalars become 1D arrays, 1D arrays become 2D arrays ([ ] -> [ [] ]). But when I use the set_val() method this doesn't happen. I am somehow not using these methods correctly but I don't know how. Any help would be greatly appreciated.

I am working in Windows 10 and fxpmath version is 0.4.9.

import numpy as np
from fxpmath import Fxp

# Create a variable a.
a = Fxp(-0.635 * np.ones(3), dtype='fxp-s16/14')
print('a = ')
a.info()

# Create a variable b.
b = Fxp(0, like=a)
print('Original b = ')
b.info()

# Change the value of b to be equal to a in two different ways.
b.set_val(a)
# b.equal(a)
print('After changing value of b = ')
b.info()
print(b.shape)
