How to resolve the algorithm Literals/Floating point step by step in the Quackery programming language

Table of Contents

Problem Statement

Programming languages have different ways of expressing floating-point literals.

Show how floating-point literals can be expressed in your language: decimal or other bases, exponential notation, and any other special features. You may want to include a regular expression or BNF/ABNF/EBNF defining allowable formats for your language.

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Literals/Floating point step by step in the Quackery programming language

Source code in the quackery programming language

  [ $ \
try:
    float(string_from_stack())
except:
    to_stack(False)
else:
    to_stack(True)
 \ python ]                                      is isfloat (   $ -->   b )

 [ nextword
   dup isfloat not if
     [ $ '"f" needs to be followed by a number.'
       message put bail ]
   ' [ ' ] swap nested join
   nested swap dip join ]                    builds f       ( [ $ --> [ $ )

  [ $ \
import math
a = string_from_stack()
a = str(math.sin(float(a)))
string_to_stack(a) \ python ]                    is sin     (   $ -->   $ )
