[FIXED] tuple to numpy, data accuracy

Issue

When I convert a tuple to numpy, there is a problem with data accuracy. My code is like this:

import numpy as np
a=(0.547693688614422, -0.7854270889025808, 0.6267478456110592)
print(a)
print(type(a))
tmp=np.array(a)
print(tmp)

The result is like this:

(0.547693688614422, -0.7854270889025808, 0.6267478456110592)
<class 'tuple'>
[ 0.54769369 -0.78542709  0.62674785]

Why?

Solution

One way is to set this:

In [1039]: np.set_printoptions(precision=20)

In [1041]: tmp=np.array(a)

In [1042]: tmp
Out[1042]: array([ 0.547693688614422 , -0.7854270889025808,  0.6267478456110592])

In [1043]: tmp.dtype
Out[1043]: dtype('float64')
