WebSubnormal Numbers: When all the exponent bits are 0 and the leading hidden bit of the siginificand is 0, then the floating point number is called a subnormal number. Thus, one logical representation of a subnormal number is (–1)s × 0.f × 2 –127 (all 0s for the exponent) , where f has at least one 1 (otherwise the number will be taken as 0).
