Convert Hex to Float Calculator

To convert a hexadecimal value to a floating-point number, you can use language-specific functions or methods. In Python, you can use struct.unpack('!f', bytes.fromhex(hex_string)) where hex_string is the input hexadecimal value. This function converts the hex representation into its IEEE 754 floating-point format and returns the corresponding float value.

FAQs

How do you convert hex float to decimal? To convert a hexadecimal floating-point number to decimal, you can use the following steps:

1. Separate the hexadecimal number into its two parts: the mantissa (fractional part) and the exponent (usually indicated by ‘p’ or ‘e’ followed by an exponent value).
2. Convert the mantissa from hexadecimal to decimal.
3. Convert the exponent from hexadecimal to decimal.
4. Calculate the final decimal value by multiplying the mantissa by 16 raised to the power of the exponent.
