The IEEE ,,Standard for Binary Floating-Point Arithmetic'' (IEEE 754) was developed in the early 1980s in order to cater for consistent floating point representation in different computer architectures. If parameters are sent as floating point numbers to/from the modules, this standard applies. A floating point number is thereby represented as a 32-bit value.
| Plus/minus sign bit | Exponent | Mantissa (standardized) |
| 1 bit (bit 32) | 8 bit (bit 23.. bit 30) | 23 bit (bit 1.. bit 22) |
| s | e | f |
As the mantissa is always set to "1", only the decimals are stored, as the leading "1" does not need to be recorded. A floating point value can thus be calculated as follows:
| Sign | Exponent | Mantissa | |
| 1 bit | 8 bit | 23 bit | |
| 7/4 | 0 | 01111111 | 11000000000000000000000 |
