Issue 3 in the DFP TS (PDF page 27) could have another wording:

If the type of the formal parameter /value/ is decimal floating,
the exponent is an integral power of 10, otherwise 2.

That covers the cases:
  frexpf( 100.DF, &intexp )
  frexpd32( 100.f, &intexp )
  frexpf( 1, &intexp )
  frexpd32( 1, &intexp )

Similar wording would apply to:
  ldexp
  logb
  scalbn
  scalbln
