this calculation is simply t % 86400. But if we were to express times before 1970 using negative numbers, the"truncate towards zero" rule would give a meaningless result!
Themath.trunc()method rounds towards zero. main.py print(math.trunc(3.45))# 👉️ 3print(math.trunc(-3.45))# 👉️ -3 This approach achieves the same result as passing the result from the division to theint()class. I wrotea bookin which I share everything I know about how to...

The expression string contains only non-negative integers, , , , operators open and closing parentheses and empty spaces. The integer division should truncate toward zero. You may assume that the given expression is always valid. All intermediate results will be in the range of . ...

it will be interpreted as a complex number and the function must be called without a second parameter. The second parameter can never be a string. Each argument may be any numeric type (including complex). Ifimagis omitted, it defaults to zero and the constructor serves as a numeric conversi...
