List of 128-bit long double numerical manipulation subroutines
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.
