math.sinh
Available inall subroutines.
Computes the hyperbolic sine of its argument x
.
Parameters
x
- Floating point value representing a hyperbolic angle.
Return Value
Upon successful completion, this function returns the hyperbolic sine of x
.
If x
is math.NAN
, a NaN will be returned.
If x
is ±0, or math.POS_INFINITY
or math.NEG_INFINITY
, x
will be returned.
If x
is subnormal, a range error occurs and x
will be returned.
If the result would cause an overflow, a range error occurs and
math.POS_HUGE_VAL
or
math.NEG_HUGE_VAL
(with the same sign as
x
) will be returned.
Errors
If the x
argument is subnormal or if the result would cause an overflow, then
fastly.error
will be set to ERANGE
.
Example
declare local var.fo FLOAT;
set var.fo = math.sinh(-1);
