Bon、c'est bien simple、il semble queANTLR4génèreleschiffresenfonction de la locale、c'est-à-dire、enfrançais：avecunevirgule。Et c'est dommage、parce dans ce cas、PostScript n'en travequedalle。

あなたの問題の解決策は簡単です。ANTLR 4は、ロケールを使用して、つまりフランス語でコンマを使用して数値を生成しているようです。PostScriptはフランス語（ラテン語？）の浮動小数点数を理解しないため、残念です。

ANTLR4に報告する必要があります。

Unixでは、bashのロケールを一時的に変更できます
