How I can deny a number floating point, without using some mathematical operation (eg. :number * (-1)). ?? How can I take the first 8 bits of the number???
Could you please restate this? I can't tell what you are trying to do. Post some code (as best as you have so far) if possible. The first 8-bits of what number? char? short? long? float? double? What does "first" mean? The MSB or the LSB? - Mark
