Bracmat has no native support for floating point variables nor for the fixed point values in the conversion table. Instead this solution just applies a string comparison.
<lang bracmat>( ( convert
=
. ("0.06"."0.10")
("0.11"."0.18")
("0.16"."0.26")
("0.21"."0.32")
("0.26"."0.38")
("0.31"."0.44")
("0.36"."0.50")
("0.41"."0.54")
("0.46"."0.58")
("0.51"."0.62")
("0.56"."0.66")
("0.61"."0.70")
("0.66"."0.74")
("0.71"."0.78")
("0.76"."0.82")
("0.81"."0.86")
("0.86"."0.90")
("0.91"."0.94")
