Hi Gary If you want floats, use “.0” at the end. Yes, the “..” at the end would be a syntax error. I think most compilers/interpreters, for a literal float, require at least one digit after the decimal point. st> x := 0 0 st> x class SmallInteger st> x := 0. 0 st> x class SmallInteger st> x := 0.0 0.0 st> x class FloatD st> Sent from Mail for Windows 10 From: Gary Highberger Sent: Friday, January 22, 2021 3:27 PM To: help-smalltalk Subject: Possible Parser Issue Hello, In lines 10-14 below I think the parser is taking the decimal point to be a period. If I add a period after the decimal point I get a compile error. No biggie. Just letting everyone know. 1 Object subclass: PIDCntlr [ 2 | pgain igain dgain acc oldErr myName| 3 PIDCntlr class >> new: name [ 4 | r | 5 r := super new . 6 r init: name . 7 ^r. 8 ] 9 init: name [ 10 pgain := 0. 11 igain := 0. 12 dgain :=0. 13 acc := 0. 14 oldErr := 0. 15 myName := name . 16 ] 17 wru [ 18 ^myName 19 ] 20 ]
