decimal floating point value

基本解釋

So a floating point value again is a number with a decimal point, so it depends.
一個(gè)浮點(diǎn)型數(shù)據(jù)就是一個(gè)，帶小數(shù)點(diǎn)的數(shù)。
Converts the value of the specified decimal number to an equivalent single-precision floating-point number.
將指定的雙精度浮點(diǎn)數(shù)的值轉(zhuǎn)換為等效的單精度浮點(diǎn)數(shù)。
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.
它直接把小數(shù)點(diǎn)后面的數(shù)值丟棄掉了，因?yàn)?，憑直覺，那些整型數(shù)和結(jié)果應(yīng)該是一個(gè)浮點(diǎn)數(shù)據(jù),但是我需要一個(gè)更精確的數(shù)值。

There's no decimal point; there's no point zero; there's no floating point value, it's just a hardcoded integer.
這里沒有小數(shù)點(diǎn)，這里沒有;,這里沒有浮點(diǎn)數(shù)值，它只是一個(gè)整型數(shù)字。
