WebIn the IEEE 754-2008 standard, the 64-bit base-2 format is officially referred to as binary64; it was called double in IEEE 754-1985. IEEE 754 specifies additional floating-point formats, including 32-bit base-2 single precision and, more recently, base-10 representations. WebFloating point notation is introduced to store any number in a predefined format. In our case we focus only on 32 bit. The value of a IEEE-754 number is computed as: sign 2exponent mantissa. The sign is stored in bit 32. The exponent can be computed from bits 24-31 by subtracting 127. The mantissa (also known as significand or fraction) is ... notification message for main appraiser
