The following subroutines perform
numerical manipulation of floating-point numbers stored in the 128-bit long
double data type. These subroutines do not support the 64-bit long
double data type. Applications that use the 64-bit long double data
type should use the corresponding double-precision subroutines.
acosl | Computes the inverse cosine of a floating-point number in long double format |
asinl | Computes the inverse sine of a floating-point number in long double format |
atan2l | Computes the principal value of the arc tangent of x/y, whose components are expressed in long double format |
