I am converting an integer to a single precision floating point number.
I understand that floating point number comprises of sign bit(1 bit), exponent(8 bits) and significand(23 bits).
I can check if input < 0 and get the sign bit.
To get the exponent and mantissa, I have to convert the integer to binary.
I am using the function "to_unsigned" in VHDL.
The problem is since i dont know how big of an integer i can get as input, I dont know how i should declare the length of the binary vector . The integer to binary conversion could give me anywhere from a minumum of 1 bits to a maximum of (I dont know).
I would like to know how to solve this problem
