Floating-point values are typically represented as either single precision (32-bits) or double precision (64-bits). In C and C++ single precision floating-point variables are typically declared as float type and double precision floating-point variables are declared as double type. As noted in the following sections, assembly language instructions will use an s (lower-case letter S) qualifier to refer to single precision and a d (lower-case letter D) qualifier to refer to double precision.
