Mathematics and compare-operators,
The most important operator is the =-operator.
Mathematical-operators
It places the value on its right to the value on its left.
Example:
number=2
A + B add A - B Subtracks A * B Multiplies A / B Divides A ^ B A raised to the Bth power -A negation, positive becomes negative and negative becomes positive A MOD B rest of A/B A \ B The quotient (whole number) of a A/B compare-operators
The result of a comparison has always the value TRUE or FALSE.
= equals < smaller then <= smaller or equal then <> different then > larger then >= larger or equal then Logic-operators
They combine the results of comparisons.
C1 AND C2 The comparisons must both be TRUE, so AND can give TRUE. C1 OR C2 1 of the comparisons must be true, so OR gives TRUE NOT C The result of the comparison is reversed.
True become FALSE.Concatenate operator
To put strings together, we use the operator &.
street="somestreet" streetnr="52" completeaddress= street & streetnr
