Tiva C TM4C123x FPU Slide 3

This slide illustrates the IEEE 754 standard representing floating point numbers in single precision format. In this format, a real number is encoded using 32 bits, of which 23 bits are used to represent the fraction, 8 bits are used to represent the exponent and the remaining 1 bit is used to represent the sign. The expression to determine the decimal value of number knowing its fraction, exponent and sign bit is shown on the slide. A 32 bit number is represented on the slide in which the lower 23 bits are used for the fraction. The next 8 bits are used for the exponent and the most significant bit is used for the sign.
