calendar, but was invented by the monk Julianus. The Julian day number tells

for a given date the number of days that have passed since the creation of the world

which was then considered to have happened on 1 Jan <20>4712 at noon. E.g. the

that the floating point arithmetic in the Pentium is executed with 80 bit

code is optimized, more intermediate results are kept inside the processor
