The meaning of such a number, if the exponent bits do not represent one of the special signal values, is ±1.{mantissa}×2({exponent}-127).
This question concerns identifying the value represented by a particular value in IEEE floating-point. Our number has a sign bit of zero (meaning that the value is greater-than-or-equal-to zero), a mantissa field of 0100000000000 (thus the mantissa value is 1.012, as the 1 before the binary point is implicit), and an exponent field of 01111100 (these eight bits represent the number 124).
What is the value represented in usual, base ten, everyday terms?
