The trigonometric operators SIN, COS, and TAN

use a Taylor series. Results are calculated to seven

significant digits. The algorithm reduces the

expression to a value between zero and PI/2 and

results in a loss of precision if input_expr is large.

Relational operators (=, <>, <, etc.) return a result of

65535 if the relation is true and zero if it's false. The

result may be displayed or used in further

calculations. Beware when comparing calculated

floating-point values as rounding errors may produce

unexpected results.

Logical operators perform bitwise operations on

expressions which evaluate to valid positive intege rs

between OH and OFFFFFH (65535). All non-

integer value s are tru ncated to integers.

Hexadecimal values with a leading alpha character

must be preceded by a leading zero or B asic will

interpret your constant as a variable name. If you

supply fewer than 16 bits to NOT it will return a 16-

bit value based on the assumption the unsupplied

bits were zeros.
