Fixed Point and Floating Point Number Representations

WebA floating-point variable can represent a wider range of numbers than a fixed-point variable of the same bit width at the cost of precision. A signed 32-bit integer variable has a maximum value of 2 31 − 1 = 2,147,483,647, whereas an IEEE 754 32-bit base-2 floating-point variable has a maximum value of (2 − 2 −23) × 2 127 ≈ 3.4028235 ... WebThe largest value that an 8-bit unsigned integer can hold is 255, which in this representation would correspond to a fixed-point value of 255 256 = 0.9961. Similarly to the above, in signed Q0.7 format, there is no representation for 1.0 or 1.5. The largest 8-bit signed number is 127, which would represent 127 128 = 0.9922. how many ounces in a 1/4 tsp
