This object is designed to ease the use of fractions
Variables
numerator #numerator of fraction
denominator #denominator of fraction
Arithmetic Methods #these will all accept a scalar value or
#another fraction as an argument
plus #returns the sum of the fraction and argument
minus #returns fraction minus argument
subtractFrom #returns argument minus fraction
divBy #returns fraction divided by argument
divInto #returns argument divided by fraction
times #returns fraction times argument
compare #returns <, =, or > for the relation of fraction to argument
pow #returns fraction raised to argument, a given integer power
Other methods
reduce #reduces to lowest terms, and makes sure denominator is positive
scalar #returns the scalar value numerator/denominator
print #prints the fraction
print_mixed #prints the fractionas a mixed number
print_inline #prints the fraction like this 2/3
The fraction object stores two variables, numerator and denominator. The basic
arithmatic methods listed above can be performed on a fraction, and it can return
its own
scalar value for use with functions expecting a scalar (ie, sqrt($frac->scalar) ).
