class friendlysam.opt.LessEqual

The relation “less than or equal to”.

Examples

>>> x = Variable('x')
>>> expr = (x <= 1)
>>> expr
<friendlysam.opt.LessEqual at 0x...>
>>> expr == LessEqual(x, 1)
True
>>> x.value = 1
>>> expr.value
True

Note

There is no GreaterEqual class, but you can use the overloaded operator >=.

>>> x >= 1
<friendlysam.opt.LessEqual at 0x...>
>>> print(_)
1 <= x
>>> (x >= 1) == (1 <= x)
True
