Python operators

The representation of Python operators in Nelson.

📄 Description

Nelson facilitates the utilization of the subsequent overloaded operators:

Python Operator Symbol	Python Methods	Nelson Methods
- (unary operator)	neg	uminus, -a
+ (unary operator)	pos	uplus, +a
+ (binary operator)	add, radd	plus, +
- (binary operator)	sub, rsub	minus, -
_ (binary operator)	mul, rmul	mtimes, _
/ (binary operator)	truediv, rtruediv	mrdivide, /
== (binary operator)	eq	eq, ==
> (binary operator)	gt	gt, >
< (binary operator)	lt	lt, <
!= (binary operator)	ne	ne, ~=
>= (binary operator)	ge	ge, >=
<= (binary operator)	le	le, <=

isequal builtin is also overloaded to manage python type.

For numpy types, isequal call numpy.array_equal from python.

Others python operators are currently not supported.

💡 Example

pyrun('import numpy as np')
R = pyrun('R = np.asarray(A)', "R", 'A', magic(3))
R_A = R + R
R_B = R * 2
isequal(R_A, R_B)
