7.4.3 Fraction Mode
-------------------
Division of two integers normally yields a floating-point number if the
result cannot be expressed as an integer. In some cases you would
rather get an exact fractional answer. One way to accomplish this is to
use the ‘:’ (‘calc-fdiv’) [‘fdiv’] command, which divides the two
integers on the top of the stack to produce a fraction: ‘6 <RET> 4 :’
produces ‘3:2’ even though ‘6 <RET> 4 /’ produces ‘1.5’.
To set the Calculator to produce fractional results for normal
integer divisions, use the ‘m f’ (‘calc-frac-mode’) command. For
example, ‘8/4’ produces ‘2’ in either mode, but ‘6/4’ produces ‘3:2’ in
Fraction mode, ‘1.5’ in Float mode.
At any time you can use ‘c f’ (‘calc-float’) to convert a fraction to
a float, or ‘c F’ (‘calc-fraction’) to convert a float to a fraction.
