Instruction Description Example Reserved Word
+ Add MW00001 = MW00002 + MW00003 √
– Subtract MW00001 = MW00002 – MW00003 √
* Multiply MW00001 = MW00002 × MW00003 √
/ Divide MW00001 = MW00002 / MW00003 √
% Remainder MW00001 = MW00002 % MW00003 √
& Bit-wise AND MW00001 = MW00002 & 4096 √
│ Bit-wise OR MW00001 = MW00002 │ 4096 √
&& Inclusive AND MB000010 = MB000011 && MB000012 √
∥ Inclusive OR MB000010 = MB000011 ∥ MB000012 √
! Logical NOT MB000010 = !MB000011 √
==
Equal to right-side
value
MB000010 = MB000011 == true √
>=
Right-side value is less
than or equal to left-
side value
MB000010 = MW00020 >= MW00021 √
>
Right-side value is less
than left-side value
MB000010 = MW00020 > MW00021 √
<
Right-side value is
greater than left-side
value
MB000010 = MW00020 < MW00021 √
<=
Right-side value is
greater than or equal to
left-side value
MB000010 = MW00020 <= MW00021 √
=
Substitute left-side
value with right-side
value
MW00001 = MW00002 √
true TRUE MB000010 = MB000011 == true √
false FALSE MB000010 = MB000011 == false √
sin() SIN MW00001 = sin(MW00002) √
cos() COS MF00002 = cos(MF00004) √
atan() ARCTAN MW00001 = atan(MF00002) √
tan() TAN MW00001 = tan(MW00002) √
() Parentheses MW00001 = (MW00002 + MW00003) / MW00004 √
asin() ARCSIN MW00001 = asin(MW00002) √
acos() ARCCOS MW00001 = acos(MW00002) √
sqrt() AQRT MW00001 = sqrt(MW00002) √
abs() ABS MW00001 = abs(MW00002) √
exp() EXP MW00001 = exp(MW00002) √
log() LOG natural logarithm MW00001 = log(MW00002) √
log10()
LOG10 common loga-
rithm
MW00001 = log10(MW00002) √
