Division (/)
Structure - Math
Divide one value (integer or fl oating point) by another value. Integer division discards fractional
results. For example:
result = 76/7
will set the variable “result” to a value of 10. (The actual decimal result would be 10.857, but the
decimal part is discarded, rounding is not done.) If your application requires fractional results you can
use fl oating point numbers or the following solution.
Use a fl oating point variable instead to get the full precision.
result var fl oat
result = 76.0/7.0
Alternatively, when using integer variables multiply the dividend by 10, 100, 1000 etc. before dividing.
The result will gain extra digits of precision but must be interpreted correctly. Using the previous
example we can gain three digits of precision as follows. This is known as fi xed point division:
temp = dividend * 1000 ;dividend is now 76000
result = temp/7
The example sets “result” to a value of 10857.
High Multiplication (**)
If two long variables or constants are multiplied, the result may exceed 32 bits. Normally, the multiply
function will return the least signifi cant (lowest) 32 bits. The ** function will, instead, return the most
signifi cant 32 bits.
time = 80000 ** 80000 ; result returns high 32 bits
The value of time would be equal to 0x1 which is the high 32 bits of the result 6,400,000,000.
