numpy.trunc() in Python

numpy.trunc(x[, out]) = ufunc ‘trunc’) : This mathematical function returns the truncated value of the elements of array. The trunc of the scalar x is the nearest integer i which, closer to zero than x. This simply means that, the fractional part of the signed number x is discarded by this function.

Parameters :

a : [array_like] Input array



Return :
The truncated of each element, with float data-type

 [0.5, 1.5, 2.5, 3.5, 4.5, 10.1]

Rounded values : 
 [  0.   1.   2.   3.   4.  10.]

Input array : 
 [0.53, 1.54, 0.71]

Rounded values : 
 [ 0.  1.  0.]

Input array : 
 [0.5538, 1.33354, 0.71445]
