問(wèn)題描述
我有兩個(gè)整數(shù) x 和 y.我需要計(jì)算 x/y 作為結(jié)果，我想獲得浮動(dòng).例如，作為 3/2 的結(jié)果，我想要 1.5.我認(rèn)為最簡(jiǎn)單(或唯一)的方法是將 x 和 y 轉(zhuǎn)換為浮點(diǎn)類(lèi)型.不幸的是，我找不到一個(gè)簡(jiǎn)單的方法來(lái)做到這一點(diǎn).你能幫我解決這個(gè)問(wèn)題嗎?
I have two integers x and y. I need to calculate x/y and as outcome I would like to get float. For example as an outcome of 3/2 I would like to have 1.5. I thought that easiest (or the only) way to do it is to convert x and y into float type. Unfortunately, I cannot find an easy way to do it. Could you please help me with that?
推薦答案
您只需要將至少一個(gè)操作數(shù)強(qiáng)制轉(zhuǎn)換為浮點(diǎn)數(shù):
You just need to cast at least one of the operands to a float:
float z = (float) x / y;
或
float z = x / (float) y;
或(不必要的)
float z = (float) x / (float) y;
