220.127.116.11. Single-Extended Precision Format
- The MSB holds the sign bit.
- The exponent and mantissa fields do not have fixed widths.
- The minimum exponent field width is 11 bits and must be less than the width of the mantissa field.
- The width of the mantissa field must be a minimum of 31 bits.
The sum of the widths of the sign bit, exponent field, and mantissa field must be a minimum of 43 bits and a maximum of 64 bits. The bias for the single-extended precision format is unspecified in the IEEE-754 standard. In these IP cores, a bias of 2 (WIDTH_EXP–1)–1 is assumed for the single-extended precision format.
