NAME
+ +
+ + NaN, Inf, isNaN, isInf – not-a-number and infinity functions
+ +
+

SYNOPSIS
+ +
+ + #include <u.h>
+ #include <libc.h> +
+ + double NaN(void) +
+ + double Inf(int) +
+ + int      isNaN(double) +
+ + int      isInf(double, int)
+ +
+

DESCRIPTION
+ +
+ + The IEEE floating point standard defines values called ‘not-a-number’ + and positive and negative ‘infinity’. These values can be produced + by such things as overflow and division by zero. Also, the library + functions sometimes return them when the arguments are not in + the domain, or the result is out of range. +
+ + NaN returns a double that is not-a-number. IsNaN returns true + if its argument is not-a-number. +
+ + Inf(i) returns positive infinity if i is greater than or equal + to zero, else negative infinity. IsInf returns true if its first + argument is infinity with the same sign as the second argument.
