Outputs its unnamed argument in their order, using the margin-left: 0.25emCSS properties in all but the first, so that there will be gaps between them. The whole output has the white-space: nowrap property so that it will not be broken across several lines.
It supports up to sixteen unnamed arguments. In addition, it supports the base and e arguments which can be used for numbers in exponential notation. The base will be assumed to be 10 unless otherwise specified; a hyphen-minus "-" in the exponent will be automatically substituted by a minus sign "−". It also supports the arguments lhs and u for putting left-hand sides and units within the non-breaking span (see examples below).
