Assembler Description
3.10 Built-in Functions
The assembler supports built-in functions for conversions and transcendental
math computations. Table 3–3 describes the built-in functions. Note that
expr
must be a constant value. See Table 5–1 for a description of the assembler’s
non-mathematical built-in functions.
