A binary operation giving the signed remainder of the integer division.
X=A MOD B
MOD is defined such that,
A MOD B = A - ( A DIV B ) * B.
If you are doing integer division (DIV) of whole numbers it is often desirable to know the remainder. (A 'teach children to divide' program for instance). For example, 23 divided by 3 is 7, remainder 2. Thus,
10 PRINT 23 DIV 3 20 PRINT 23 MOD 3
would print
7
2
You can use real numbers in these calculations, but they are truncated to their integer part before BBC BASIC (Z80) calculates the result. Thus,
10 PRINT 23.1 DIV 3.9 20 PRINT 23.1 MOD 3.9
would give exactly the same results as the previous example.
