where the argument within the parentheses may be an expression. Value converters perform arithmetic translation from units of one kind to units of another. The result can then be a term in a further expression.
Note that for log, sqrt, and ftlen the argument value is restricted. Note also that ftlen will always return a power-of-2 value, i.e. the function table guard point (see F statement) is not included.
