Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
These functions return the mantissa of
x scaled to the range

scalb(x, (double) -ilogb(x))
This function exists mainly for use in certain standardized tests for IEEE 754 conformance.
These functions are nonstandard; the

available on a number of other systems.
