Share price clarification

I am a tad embarrassed about asking this but what the hell:eek:

How is 45C written up as a share price on the board?

Is .045 on the board 45c ?
so what is 0.450000 ? [i was told this is 45c]

and 0.040000 ? is this 4c

l know this is dumb of me but l have been totally confused over this:eek::eek:
.04500 is four and a half cents
.45000 is forty-five cents

some shares do trade in fractions of cents as sunfish said.

it's only dumb to NOT ask for enlightenment.:)
