*Converting 4 bytes to a 32-bit float involves interpreting the bytes according to the IEEE 754 standard. The first byte represents the sign bit, the next two bytes denote the exponent, and the last byte represents the fraction. By combining these components and applying the standard formula, you can calculate the float value.*

Byte 1 (MSB) | Byte 2 | Byte 3 | Byte 4 (LSB) | 32-bit Float Value |
---|---|---|---|---|

Sign Bit | Exponent Bits | Exponent Bits | Fraction Bits | Float Value |

Here’s a breakdown of each part:

**Sign Bit (Byte 1):**The leftmost bit (most significant bit – MSB) represents the sign of the float. If it’s 0, the float is positive; if it’s 1, the float is negative.**Exponent Bits (Byte 2 and Byte 3):**The next 8 bits represent the exponent of the float. These bits are split between Byte 2 and Byte 3. Interpret them as an unsigned binary number. You may need to subtract a bias value (usually 127 for single-precision) to get the actual exponent.**Fraction Bits (Byte 3 and Byte 4 – LSB):**The remaining 23 bits represent the fraction or mantissa. These bits are split between Byte 3 and Byte 4 and are used to represent the fractional part of the float.**32-bit Float Value:**Using the sign, exponent, and fraction bits, you can calculate the final 32-bit float value. The sign determines whether it’s positive or negative, the exponent provides the scale, and the fraction represents the precision.

To calculate the final float value, you would perform bit manipulations and mathematical operations based on the IEEE 754 standard for single-precision floating-point numbers.
