numeric_limits::is_iec559
Tests if a type conforms to IEC 559 standards.
static const bool is_iec559 = false;
Return Value
true if the type conforms to the IEC 559 standards; false if not.
Remarks
The IEC 559 is an international standard for representing floating-point values and is also known as IEEE 754 in the USA.
