This isn’t a problem strictly related to binary search in Python, as the built-in linear search is consistent with it: Python >>> 0.1 in sorted_numbers True >>> 0.2 in sorted_numbers True >>> 0.3 in sorted_numbers False It’s not even a problem related to Python but rather to...
In the second example, the same symbol is a binary operator, and the numbers 5 and 2 are its left and right operands. Programming languages typically have operators built in as part of their syntax. In many languages, including Python, you can also create your own operator or modify the ...
The decimal module offers a Decimal datatype for decimal floating point arithmetic. Compared to the built-in float implementation of binary floating point, the class is especially helpful forfinancial applications and other uses which require exact decimal representation, control over precision, control...
