Mar 02, 2017 Program for Exponential Series in C is used to calculate the value of exp(x) for n number of terms using for loop and prints it in the output screen. Contact Us Privacy. Mar 02, 2017 Before going to the program for Exponential Series first let us understand what is a Exponential Series? Exponential Series: Exponential Series is a series which is used to find the value of e x. The formula used to express the e x as Exponential Series is. Expanding the above notation, the formula of Exponential Series is. The exp function computes, the base-e exponential of x. The exp2 function computes, the base-2 exponential of x. The expm1 function computes the base-e exponential of x, minus 1, accurately even for very small values of x.

template<class T > complex<T> exp(const complex<T>& z ); |
Compute base-e exponential of z, that is e (Euler's number, 2.7182818) raised to the z power.
[edit]Parameters
| z | - | complex value |
Dev C Exponential Function Definition
[edit]Return value
If no errors occur, e raised to the power of z, ez
, is returned.
[edit]Error handling and special values
Errors are reported consistent with math_errhandling
If the implementation supports IEEE floating-point arithmetic,
- std::exp(std::conj(z))std::conj(std::exp(z))
- If
zis(±0,+0), the result is(1,+0) - If
zis(x,+∞)(for any finite x), the result is(NaN,NaN)and FE_INVALID is raised. - If
zis(x,NaN)(for any finite x), the result is(NaN,NaN)and FE_INVALID may be raised. - If
zis(+∞,+0), the result is(+∞,+0) - If
zis(-∞,y)(for any finite y), the result is+0cis(y) - If
zis(+∞,y)(for any finite nonzero y), the result is+∞cis(y) - If
zis(-∞,+∞), the result is(±0,±0)(signs are unspecified) - If
zis(+∞,+∞), the result is(±∞,NaN)and FE_INVALID is raised (the sign of the real part is unspecified) - If
zis(-∞,NaN), the result is(±0,±0)(signs are unspecified) - If
zis(+∞,NaN), the result is(±∞,NaN)(the sign of the real part is unspecified) - If
zis(NaN,+0), the result is(NaN,+0) - If
zis(NaN,y)(for any nonzero y), the result is(NaN,NaN)and FE_INVALID may be raised - If
zis(NaN,NaN), the result is(NaN,NaN)
where cis(y) is cos(y) + i sin(y)
[edit]Notes
The complex exponential function ez
for z = x+iy equals ex
cis(y), or, ex
(cos(y) + i sin(y))
The exponential function is an entire function in the complex plane and has no branch cuts.
