Question

The format of the single-precision floating-point representation of a real number as per the IEEE 754 standard is as follows:

sign

exponent

mantissa

Which one of the following choices is correct with respect to the smallest normalized positive number represented using the standard?
1. exponent = 00000000 and mantissa = 00000000000000000000001
2. exponent = 00000001 and mantissa = 00000000000000000000000
3. exponent = 00000001 and mantissa = 00000000000000000000001
4. ​exponent = 00000001 and mantissa = 000000000000000000000001

Answer 1

Correct Answer - Option 2 : exponent = 00000001 and mantissa = 00000000000000000000000

​exponent = 00000000 and mantissa = 00000000000000000000000
