Question

I know is simple and I know that is asked many times but still I couldn t find the thing I am looking for.

I have a value from 0 to 500 it is a int. I want to have an output from 0x00 to 0xFF.

public void method(int i)// 0-500
{
return the_proportional_value_in_hex_in_range_0_to_ff;
}

任何人可以把我从这种转变中带走。增编

EDIT

I DO NOT希望进行准确的转换,我只想进行静脉注射器转换,@Mac对我所需要的准确回答。

Answer 1

<代码>i / 500code>/code> to the range 0 ...... 1, 然后乘以255(即0xFF>,到 255。取而代之(多,然后是分裂)只是防止数字鸿沟出现数字不足。

印刷时,可使用<代码>System.out.printf(“%x”),按比例计算;。我说是印刷的,因为谈论“高价值”是非常有用的。

Answer 2

巴勒克不可能。你们需要9个参照点,即500 = 0x1F4。
