Sofus is a programming language, inspired by Cobol, but object-programmed. It has variables, which have a value (a float), and can be inverted or raised by or lowered by or multiplied by or divided by or raised to the power, any constant increment/factor/power, or any other variable. Try for example
price = Variable(100) for n in range(100): price.raise_by(1,percents)
percents = "percents" thesquare = 2 thecube = 3 def thepower(n): return n class Variable(): def __init__(self,v): self.value = float(v) def __str__(self): return str(self.value) def __repr__(self): return str(self.value) def raise_by(self,d=1,mode=None): if hasattr(d,'value'): d = d.value if mode == None: self.value += d elif mode == percents: self.value *= 1+d/100 def lower_by(self,d=1,mode=None): if hasattr(d,'value'): d = d.value if mode == None: self.value -= d elif mode == percents: self.value *= 1-d/100 def multiply_by(self,d=2,mode=None): if hasattr(d,'value'): d = d.value if mode == None: self.value *= d elif mode == percents: self.value *= d/100 def divide_by(self,d=2,mode=None): if hasattr(d,'value'): d = d.value if mode == None: self.value /= d elif mode == percents: self.value /= d/100 def raise_to(self,power=thesquare): if hasattr(power,'value'): power = power.value self.value **= power def invert(self): self.value = 1/self.value
