# 7. Error Functions, Dawson’s and Fresnel Integrals

$C\left(x\right)$ denotes the Fresnel integral $C$; see DLMF (7.2.7).
Computations are currently restricted to real values of $x$, with $|x|\le 1$.
Evaluate $C\left(x\right)$ as a Tabulation or Comparison?
Get function arguments from form or data file?
Specify the data file to compare tofor arguments:
Note: The lines in the data file must contain values for $x$ and $C\left(x\right)$ in that order, separated by commas or spaces.
Specify grid for function parameters and arguments:
Choose $x$ starting from ending with stepping by
Show output to digits, the number of digits in file, using
Return unformatted output only
