一般而言,十进位浮点数值并没有精确的二进位表示式。
Floating-point decimal values generally do not have an exact binary representation.
将指定的单精确度浮点数值的文字表示写入标准输出资料流。
Writes the text representation of the specified 32-bit unsigned integer value to the standard output stream.
如果该数值位于PHP允许的浮点数值范围之内,那么它就是有限值。
The value is finite if it is within the allowed range for a PHP float on this platform.
C So here I'm declaring a variable called c, and I'm pretty much translating the formula from the slide using the characters on my keyboard to a floating point value.
这里我声明了一个变量,然后我把那个幻灯片上的公式,用键盘上的字符翻译成了,浮点数值。
It just throws the decimal point away and that's because, again, these are ints and the answer intuitively should be a floating point value, but I need to be more specific.
它直接把小数点后面的数值丢弃掉了,因为,凭直觉,那些整型数和结果应该是一个浮点数据,但是我需要一个更精确的数值。
There's no decimal point; there's no point zero; there's no floating point value, it's just a hardcoded integer.
这里没有小数点,这里没有;,这里没有浮点数值,它只是一个整型数字。
