- float: float是浮点数（floating-point number）的缩写，代表浮点数类型。它指的是具有小数部分的数字。例句:- int: 我的年龄是25岁。 (My age is 25.)- float: 我的体重是63.5公斤。 (My weight is 63.5 kilograms.)2. 用法区别:- int: int通常用于表示整数值，例如计数、索引等。- ...
IEEE754binaryfloatingpointrepresentation之下，32位floatpointnumber，最左边一位（bit31）表示符号（正负），接下来8位（bit30－23）表示指数，剩下23位（bit22－0）表示数值（比较复杂，具体见公式）。（－1）＾s×（1＋m／2＾23）×2＾（e－127）s是第一位，e是8位指数，m是数值。可表示的范...
The least positive number. static var zero: Self The zero value. Working with Binary Representation var bitPattern: UInt32 The bit pattern of the value’s encoding. var significandBitPattern: UInt32 The raw encoding of the value’s significand field. var significandWidth: Int The number of bi...
当小数域为非零时,结果值被称为 NaN (Not a Number ),即 "不是一个数" 。 一些运算的结果不能是实数或无穷,就会返回一个 NaN 值, 比如当计算 或 时。 0x09 Tiny Floating Point Example 八位浮点数表示法 与IEEE格式差不多,规范化值、非规范化值。
Python's float supports special values like infinity and NaN (Not a Number). This example demonstrates their creation and checking. special_values.py # Infinity pos_inf = float("inf") neg_inf = float("-inf") print(pos_inf, neg_inf) # inf -inf # NaN (Not a Number) nan = float(...
To be finite a number mustn't be a NaN or +/- inf. A result of True guarantees that the number is bounded by +/- inf, -inf < x < inf. Parameters: obj (float) - A python float object. Returns: bool True if the float is finite. Raises: TypeError - If the input object isn'...
The binary representation of floating-point numbers canonly store a finite number of digits, which means that some numbers cannot be represented exactly. As a result, when performing calculations with these numbers, errors can accumulate and lead to unexpected results. 浮点条件可能是由于浮点数的有限...
