EXP(X)

Purpose

Exponential.

Class

Elemental function

Argument type and attributes

X: An INTENT(IN) REAL or COMPLEX

Result type and attributes

Same as X.

Result value

The result approximates e^x.
If X is of type complex, its real and imaginary parts are regarded as values in radians.

Examples

EXP (1.0) has the value 2.7182818 (approximately).

Specific Name	Argument Type	Result Type	Pass As Arg?
EXP 1	default real	default real	yes
DEXP 2	double precision real	double precision real	yes
QEXP 2 3	REAL(16)	REAL(16)	yes
CEXP 4a	default complex	default complex	yes
CDEXP 4b 3	double complex	double complex	yes
ZEXP 4b 3	double complex	double complex	yes
CQEXP 4b 3	COMPLEX(16)	COMPLEX(16)	yes

Note:

X must be less than or equal to 88.7228.
X must be less than or equal to 709.7827.
IBM extension.
When X is a complex number in the form a + bi, where i = (-1) ^½:
1. a must be less than or equal to 88.7228; b is any real value.
2. a must be less than or equal to 709.7827; b is any real value.
