If you want conversion of a string to a BigDecimal that returns 0 rather than raising on bad input, you have String#to_d in `bigdecimal/util`. That's consistent with String#to_f and #to_i as well. But there is currently no way to do a conversion that raises, BigDecimal() is inconsistent with Float() and Integer() -- https://bugs.ruby-lang.org/ Unsubscribe:
