3/8 is not a fraction. Yes, in a text paragraph like this one I might
write 3/8 as a fraction because I can't write a superscript three over
a subscript eight, but in an arithmetic expression 0.375 is a fraction
and 3/8 is "integer 3 divided by integer 8", and the definition of
"divided by" includes "if both numerator and denominator are integers,
then the result must also be an integer". As has been mentioned, this
is the way a LOT of programming languages work.
