int bin = 0 b1101_0010_1011_0100; int hex = 0 x2F_BB_4A_F1; int dec = 1 _000_500_954; double real = 1 _500. 200 _2e-1 _000; Generally, it may be put only between digit characters. It cannot be put at the beginning ( _121 ) or the end of the value ( 121_ or 121.05_ ), next to the decimal in floating point values ( 10_.0 ), next to the exponent ...

In computer architecture, predication is a feature that provides an alternative to conditional transfer of control, as implemented by conditional branch machine instructions. Predication works by having conditional ( predicated ) non-branch instructions associated with a predicate , a Boolean value used by the instruction to control whether the ...
