# Well, you could provide your formula as strings and convert it to
# something that creates BigDecimals along the way, like
# irb(main):015:0> "0.01+0.05".gsub(%r{\d+(?:\.\d*)?}, 
# "BigDecimal.new('\\&')")
# => "BigDecimal.new('0.01')+BigDecimal.new('0.05')"
# irb(main):016:0> eval("0.01+0.05".gsub(%r{\d+(?:\.\d*)?},
# "BigDecimal.new('\\&')"))
# => #<BigDecimal:7ff6dd60,'0.6E-1',4(12)>
# note this is of course not a proper solution since the RX does not
# match all valid floats

:)
on my case, i just want ruby to default to bigdeci (or whatever i want) instead of float. meaning, i choose any math processor i want. is that possible now, or in near future of ruby?
