STANDARDS CONFORMANCE
This file conforms to the XPG4 version 2 specification when used for IEEE floating-point data.
Remember the following rules when using any special floating-point mode:
• Do not assume that functions such as printf( ) or tanh( ) behave correctly if you call
them after setting a nondefault mode (such as rounding toward zero). Unless a function
is documented as tolerating such settings, you should restore the default operating mode
before calling the function.
• The exception bits of the status register stay set until they are explicitly cleared.
