Part of the computer that actually performs arithmetic and logical operations on data. Lecture 8. Floating point format. Review. Two’s complement. Excessive notation. Introduction to floating point. Outline. Floating point conversion process. Standards. What are the components that make up a floating point number?. Convert Unsigned Floating-Point Binary 10111101.101110112 to Decimal Solution: The integer portion is evaluated as an unsigned integer: 101111012 Original Integer decimal = 1*27 + 0*26 + 1*25 + Floating Point.
