integer-decode-float x[Function]

Returns three values:

  1. An integer representation of the significand.

  2. The exponent for the power of 2 that the significand must be multiplied by to get the actual value. This differs from the decode-float exponent by float-digits , since the significand has been scaled to have all its digits before the radix point.

  3. -1 or 1. i.e. the sign of the argument.
