-1.625.
For IEEE Single precision floating point representation:
Sign is 1 bit followed by exponent(8 bits) followed by Mantissa(23 bits)
Representation is (-1)^(Sign_bit) * (1.Mantissa) * 2^(Exponent-127)
Exponent=01111111=127 in decimal.
So value=(-1)^1 * (1.101000000....0) * 2^(127-127)
= - 1 * 1.101 * 2^0 ....(in binary)
= -1 * 1.625 ...(in decimal)
= - 1.625
