Description:
A non-recursive alternative to BitTest.
Bits are numbered from zero.
Div ( value ; 2 ^ bit ) is odd if the tested bit is set,
lower bits that are set add zero to the result,
higher bits that are set add an even number to the result.
If required, you could add error checking to make sure bit and value are >= 0.
Alternatively, you can use the function as is to test bits in the fractional part of the value or to test negative values.
