Description

At the moment the coercion from Number to Boolean is implemented as

public Boolean coerce(Number input)
{
return input.byteValue() != 0;
}

It should be

public Boolean coerce(Number input)
{
return input.longValue() != 0;
}

All numbers (e.g. longs, integers, shorts) will be coerced to false if the number modulo 256 is zero.
