-FUNCTION
-	<<exp>>, <<expf>>---exponential
-INDEX
-	exp
-INDEX
-	expf
-
-ANSI_SYNOPSIS
-	#include <math.h>
-	double exp(double <[x]>);
-	float expf(float <[x]>);
-
-TRAD_SYNOPSIS
-	#include <math.h>
-	double exp(<[x]>);
-	double <[x]>;
-
-	float expf(<[x]>);
-	float <[x]>;
-
-DESCRIPTION
-	<<exp>> and <<expf>> calculate the exponential of <[x]>, that is, 
-	@ifinfo
-	e raised to the power <[x]> (where e
-	@end ifinfo
-	@tex
-	$e^x$ (where $e$
-	@end tex
-	is the base of the natural system of logarithms, approximately 2.71828).
-
-	You can use the (non-ANSI) function <<matherr>> to specify
-	error handling for these functions.
-
-RETURNS
-	On success, <<exp>> and <<expf>> return the calculated value.
-	If the result underflows, the returned value is <<0>>.  If the
-	result overflows, the returned value is <<HUGE_VAL>>.  In
-	either case, <<errno>> is set to <<ERANGE>>.
-
-PORTABILITY
-	<<exp>> is ANSI C.  <<expf>> is an extension.
