Default number radix modifier: changes the value of the default radix assumed for any numeral lacking an explicit radix within the following text, until another {ju'ai} appears.
By default, the number radix is deduced from context; it is always possible to restore a context-dependent default with xo'e ju'ai or no'o ju'ai. pa no ju'ai isn't a good usage because pa no's interpretation depends on the current default radix; dau ju'ai should be preferred. For setting hexadecimal as the default, you may use bi pi'i re ju'ai.
