floating point - IEEE 64 and 32 bit float validation in OCaml -

i have string matching following regex \-?[0-9]*\.[0-9]+ supposedly represents ieee floating point number. single or double precision , know type in advance. need check if interpreted valid value in given precission. like: val is_valid_float: string -> bool val is_valid_double: string -> bool for double precision numbers, can parse using float_of_string , catch exception. unsure how deal single precision. @jonathanchan's comments enlightening, more might say. however, i'm not sure mean validation. is "1.0000000000000001" valid float? val f : string = "1.0000000000000001" # float_of_string f;; - : float = 1. # there's no exception indicate number can't represented distinct 1.0. if ignore issues of precision, might not difficult test against representable range string operation. as @jonathanchan points out, best answer depends on how sure need (and want sure of, exactly).

javascript - undefined and NaN, convert to boolean value implicitly vs explicitly -

i'm learning javascript following book "you dont know js". in section " type & grammer ", when discussing implicit vs explicit boolean convertion, author mentioned //come function make sure 1 argument truthy //implicit convertion function onlyone() { var sum = 0; (var i=0; < arguments.length; i++) { // skip falsy values. same treating // them 0's, avoids nan's. if (arguments[i]) { sum += arguments[i]; } } return sum == 1; } //explicit convertion function onlyone() { var sum = 0; (var i=0; < arguments.length; i++) { sum += number( !!arguments[i] ); } return sum === 1; } is explicit coercion form of utility "better"? avoid nan trap explained in code comments. but, ultimately, depends on needs. think former version, relying on implicit coercion more elegant (if won't passing undefined or nan ), , explicit version needlessly more verbose. my questi...
