I think it's more specifically an R6RS thing. Quoth the standard: In systems with inexact number objects of varying precisions, it may be useful to specify the precision of a constant. For this purpose, representations of number objects may be written with an exponent marker that indicates the desired precision of the inexact representation. The letters s, f, d, and l specify the use of short, single, double, and long precision, respectively. (When fewer than four internal inexact representations exist, the four size specifications are mapped onto those available. For example, an implementation with two internal representations may map short and single together and long and double together.) In addition, the exponent marker e specifies the default precision for the implementation. The default precision has at least as much precision as double, but implementations may wish to allow this default to be set by the user. http://www.r6rs.org/final/html/r6rs/r6rs-Z-H-7.html#node_sec_4.2.8 Cheers, Asumu -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
