Source sentences:
text: MATLAB represents infinity by the special value inf , and values that are neither real nor complex by the special value NaN , which stands for “Not a Number”.
text: The case of even v (and, hence, odd u) cannot be treated this way within the reals, since there is no real number x such that x2k = −1, the value of bu/v in this case must use the imaginary unit i, as described more fully in the section § Powers of complex numbers.
text: The roots r of factors of degree one are necessarily real, and replacing x by r gives an embedding of F into R; the number of such embeddings is equal to the number of real roots of f. Restricting the standard absolute value on R to F gives an archimedean absolute value on F; such an absolute value is also referred to as a real place of F.
