Dear Holger, I've checked the Float class source and narrowed the error to this scenario, which is a differend code point but raises the same error:
(start gst in command line and enter the following:) 2 raisedToInteger: (-0.00019623982224262149) exponent - (-0.00019623982224262149) class precision + 1 Going into details: st>(-0.00019623982224262149) exponent -13 st> (-0.00019623982224262149) class precision 53 st> (-0.00019623982224262149) class precision + 1 54 So, -13 - 54 = -67 2^(-67) with calculator: 2^(-67) = 6.7762636e-21 Evaluating the following leads to the same: st> 2 raisedToInteger: -67 Object: 1 error: The program attempted to divide a number by zero ZeroDivide(Exception)>>signal (ExcHandling.st:254) SmallInteger(Number)>>zeroDivide (SysExcept.st:1386) Fraction>>setNumerator:setDenominator: (Fraction.st:485) Fraction class>>numerator:denominator: (Fraction.st:66) Fraction>>raisedToInteger: (Fraction.st:510) SmallInteger(Number)>>raisedToInteger: (Number.st:922) UndefinedObject>>executeStatements (a String:1) best regards Robert 2016-07-06 12:08 GMT+02:00 Holger Freyther <hol...@freyther.de>: > > > On 06 Jul 2016, at 10:44, Robert Kuszinger <kuszin...@giscom.hu> wrote: > > > > Hello! > > > > I've made a script to perform GRASS GIS operations automatically. > > It was running for weeks nicely. > > > > Today it emerged: > > > > Object: 1 error: The program attempted to divide a number by zero > > > > > ZeroDivide(Exception)>>signal (ExcHandling.st:254) > > SmallInteger(Number)>>zeroDivide (SysExcept.st:1386) > > Fraction>>setNumerator:setDenominator: (Fraction.st:485) > > Fraction class>>numerator:denominator: (Fraction.st:66) > > Fraction>>raisedToInteger: (Fraction.st:510) > > so the denominator is 0?
