Defined in header <cmath>
​float       exp( float arg );​
​double      exp( double arg );​
​long double exp( long double arg );​

Computes the e (Euler's number, 2.7182818) raised to the given power arg

[edit] Parameters

arg

-

floating point value

[edit] Return value

e raised to the power arg

If the result is too large for the underlying type, range error occurs and ​HUGE_VAL​ is returned.

[edit] See also

log	natural logarithm (to base e) (function)
pow	returns the given number raised to the given power (function)
