Usage notes

 * Use with ordinal numbers (first, tenth, hundredth) is somewhat more common and formal for positive integers.
 * For negative, zero, or fractional powers, the ordinal form (minus tenth, zeroth, halfth) is rare or non-existent without the word "power".
 * The use with cardinal numbers (one, ten, one hundred, zero, minus ten) is common in Mathematics and Computing and is almost always used for numbers other than positive integers.
 * Formal usage with ordinals normally includes the word "power" for clarity, and the alternative form is preferred for powers that are not positive integers.
