1) In a computer that handles real numbers, what data is stored in the mantissa and in the exponent?

2) What is the connection between the resolution of a screen and its bit-map?

3) How are vector graphics stored in the memory?

Thanks for any help at all, and sorry if this is in the wrong section but it didn't seem relevant to the other sections.

These are not normal computing questions, and sound suspiciously like homework questions. We don't help with homework. If it's homework, you're welcome to search the wide world of the internet to find your answers. If it's not homework, you may still search, but perhaps someone will read this and be able to help you.

Real number
Complex number (which i always learned as "non-real numbers")

Ok Im with you to that point but why would a computer only use one or the other?

1. The mantissa stores the fractional part and the exponent stores the power of 2 to which the mantissa is raised.
E.g. If the mantissa is: 01100000 (3/4) and the exponent is 00000110 (6) then it's 3/4 * 2^6 = 48

2. A bit-map is a 2D array of pixels. The larger the screen resolution, the larger the bit-map since there are more pixels to "map".

3. 3 things are stored: the x co-ordinate, the y co-ordinate and the colour.
