eve::conditional_expr
Specifies that a type is a Conditional Expression.

eve::cscd
constexpr auto cscd
elementwise_callable object computing the cosecant from an input in degree.
Definition:
cscd.hpp:75
eve::quarter_circle
constexpr quarter_circle_type const quarter_circle
Higher-order Callable Object imbuing a limited range semantic onto other Callable Objects.
Definition:
trigo_tags.hpp:159
eve
EVE Main Namespace.
Definition:
abi.hpp:18
Parameters
x
:
floating value
.
c
: Conditional expression masking the operation.
m
: Logical value masking the operation.
Return value
Returns the
elementwise
cosecant of the input expressed in degree (the inverse of the sine). In particular:
If the element is \(\pm0\), \(\pm\infty\) is returned.
If the element is \(\pm\infty\), Nan is returned.
If the element is a
NaN
,
NaN
is returned.
The operation is performed conditionnaly
.
Assumes that the inputs elements belong to \([-45,45]\) and return NaN outside.
