Convert binary floating-point real numbers into

denary and vice versa

Normalise floating-point numbers Show understanding of the consequences of a

Show understanding that binary representations

can give rise to rounding errors

Use two’s complement form

Understand of the effects of changing the allocation

of bits to mantissa and exponent in a floating-point

representation
