WebDec 9, 2014 · I am using the boost::multiprecision library for decimal float types, and wish to compare two floats to the specified precision. However, cpp_dec_float seems to compare the number not to the specified precision, but also includes the guard digits: WebAll of the non-member integer operations are overloaded for the fundamental (built-in) integer types in < boost / multiprecision / integer. hpp >. Where these operations require a temporary increase in precision (such as for powm ), then if no fundamental (built-in) type is available, a cpp_int of appropriate precision will be used.
