Syntax of Math.floor() is Math.floor(). Follow answered Jan 29, 2019 at 21:03. Here, we will see how to convert float list to int in python. For example, pow(-9, 0.5) returns a value close to 3j. In doing so, the function preserves the sign value of the number. Like int(), float() cant convert a complex either. Required fields are marked *. For a negative base of type int or float and a non-integral exponent, a complex result is delivered. import numpy as np list_ex = [1, 0] # This a list list_int = np.array(list_ex) # This is a numpy integer array If you want to convert the integer array to a floating array then add 0. to it. Floor division works well when you only need the nearest whole number, or when you know that there will be no remainder. Convert a string to int: int(); Convert a string to float: float(); Convert a string of binary, octal, and hexadecimal notation to int; Convert a string of exponential notation to float; Use str() to convert an Context precision and rounding come into play during arithmatic operators.
