Re: [netmod] Question on YANG 'fraction-digit' statement
Hi Martin, Thanks - yes, that makes sense.

If fraction-digits is 2, it means, according to section 9.3 in RFC 7950, that the value space consists of the real numbers that are expressible as "i x 10^-2", where "i" is a 64-bit integer. 123.45678 cannot be expressed in this way, which means that it is not a valid value for this type. /martin ___ netmod mailing list netmod@ietf.org https://www.ietf.org/mailman/listinfo/netmod
