`"EXTENSIONS"` it's inverse is `F>S` - convert a cell parameter to floating-point. primitive code = [p4_nofp_s_to_f] `FTRUNC>S``(f: x -- s: n )``` => `"EXTENSIONS"` The word `F>S` was sometimes defined with a different behavior than `FTRUNC>S` which is the type-cast behaviour of C according to C99 section 6.3.1.4 - truncation would also match the ANS-Forth specification for `F>D`. Some systems used `F>S` defined to `FROUND>S` instead. The pfe provides explicit words for both conversions, the word `FROUND>S` and `FTRUNC>S` which return single-cell parameters for a floating point number with the conversion method of `FTRUNC` or `FROUND`. In PFE, `F>S` is a synonym pointing to `FTRUNC>S` in analogy of the behavior of `F>D` where no explicit word exists. The inverse of `F>S` is the cast conversion of `S>F`. primitive code = [p4_nofp_f_trunc_to_s] `FROUND>S``(f: x -- s: n)``` => `"EXTENSIONS"` complements `FTRUNC>S` for applications that expect `F>S` to be defined with a rounding behavior like
        : FROUND>S FROUND FTRUNC>S ;
  primitive code = [p4_nofp_f_round_to_s] `FTRUNC``(f: x -- x' )``` => `"EXTENSIONS"` truncate towards zero, discard a fractional part. See also `FTRUNC>S` conversion and the `FROUND` and `FLOOR` adaptors.
        : FTRUNC FDUP F0< IF FCEIL ELSE FLOOR THEN ;
(When available, uses a single call to C99 trunc() internally) primitive code = [p4_nofp_f_trunc] `-FROT``(f: x1 x2 x3 -- x3 x1 x2 )``` => `"EXTENSIONS"` F-stack equivalent of `-ROT` note, some systems call this work F-ROT, here it is the inverse of `FROT` primitive code = [p4_nofp_minus_f_rot] `FNIP``(f: x1 x2 -- x2 )``` => `"EXTENSIONS"` F-stack equivalent of `NIP` primitive code = [p4_nofp_f_nip] `FTUCK``(f: x1 x2 -- x2 x1 x2 )``` => `"EXTENSIONS"` F-stack equivalent of `TUCK` primitive code = [p4_nofp_f_tuck] `1/F``(f: x -- 1/x )``` => `"EXTENSIONS"` primitive code = [p4_nofp_one_over_f] `F^2``(f: x -- x^2 )``` => `"EXTENSIONS"` primitive code = [p4_nofp_f_square] `F^N``( u f: x -- x^u )``` => `"EXTENSIONS"` For large exponents, use F** instead. Of course u=-1 is large. primitive code = [p4_nofp_f_power_n] `F2/``(f: x -- x/2 )``` => `"EXTENSIONS"` primitive code = [p4_nofp_f_two_slash] `F2*``(f: x -- x*2 )``` => `"EXTENSIONS"` primitive code = [p4_nofp_f_two_star] `F0>``(f: x -- s: flag )``` => `"EXTENSIONS"` primitive code = [p4_nofp_f_zero_greater] `F0<>``(f: x -- s: flag )``` => `"EXTENSIONS"` primitive code = [p4_nofp_f_zero_not_equal] `MAX-FLOAT``` => `"EXTENSIONS"` (no description) primitive code = [p__nofp_max_float]
