IEEE floating point numbers have three basic components: the sign, the exponent, and the mantissa. The mantissa is composed of the fraction and an implicit leading digit (explained below). The exponent base (2) is implicit and need not be stored.

The rules for converting a decimal number into floating point are as follows: ... Place the mantissa into the mantissa field of the number. Omit the leading one, and fill with zeros on the right. ... Add the bias to the exponent of two, and place it in the exponent field. The bias is 2k−1 − 1, where k is the number of bits...

Increase the mantissa size from 1 to 2. You will notice that the result is still too large to represent as a floating-point number. The mantissa size has no effect on overflow errors; only on roundoff errors.

Floating-point numbers have multiple representations, because one can always multiply the mantissa of any floating-point number by some power of the radix and change the exponent to get the original number. For example, the number -5 can be represented equally by any of the following forms in radix 10: ... Add comment...

Here's how to add floating point numbers. ... Adding two floating point values isn't so difficult. It basically consists of adjusting the number with the smaller exponent (call this Y) to that of the larger (call it X), and shifting the radix point of the mantissa of the Y left to compensate.

There are four opeartions: load register, get register, floating point add, and floating point subtract. The operand size are: 7 mantissa bits, 3 exponent bits, and a sign bit. Normalized input is assumed, and the chip also outputs a normalized input.
