Types
A collection of mathematical functions that return floats. Arguments are numbers.
erf(X) -> float()
|
Types
Returns the error function of X
, where:
erf(X) = 2/sqrt(pi)*integral from 0 to X of exp(-t*t) dt.
erfc(X) -> float()
|
Types
erfc(X)
returns 1.0
- erf(X)
, computed by methods that avoid cancellation for large X
.
pi() -> float()
|
A useful number.
Limitations
As these are the C library, the same limitations apply.
