13.5.5 Arithmetic commands

A variety of arithmetic operations can be performed between variables.
Command format
#i = <formula>
<Formula> is a combination of constants, variables, functions and operators.
Constants can be used instead of #j and #k below.
(1) Definition and
substitution of variables
(2) Addition arithmetic
(3) Multiplication arithmetic
(4) Functions
(Note 1) A value without a decimal point is basically treated as a value with a decimal point at the
(Note 2) Offset amounts from #10001 and work coordinate system offset values from #5201 are
(Note 3) The <formula> after a function must be enclosed in the square parentheses.
#i = #j
#i = #j + #k
#i = #j – #k
#i = #j OR #k
#i = #j XOR #k
#i = #j ∗ #k
#i = #j / #k
#i = #j MOD #k
#i = #j AND #k
#i = SIN [#k]
#i = COS [#k]
#i = TAN [#k]
#i = ATAN [#j]
#i = ACOS [#j]
#i = SQRT [#k]
#i = ABS [#k]
#i = BIN [#k]
#i = BCD [#k]
#i = ROUND [#k] Rounding off
#i = FIX [#k]
#i = FUP [#k]
#i = LN [#k]
#i = EXP [#k]
end (1 = 1.000).
handled as data with a decimal point. Consequently, data with a decimal point will be
produced even when data without a decimal point have been defined in the variable
numbers.
(Example)
#101 = 1000 ;
#10001 = #101 ;
#102 = #10001 ;
