6.7.2  Integer and fractional part: propfrac propFrac

Rational numbers are often broken up into integer and fractional parts, where the fractional part has absolute value less than 1; i.e., the absolute value of the top integer is smaller than that of the bottom integer. Such a fraction is called a proper fraction. The propfrac command writes a fraction as an integer plus a proper fraction.
propFrac is a synonym for propfrac.

(For rational expressions, see Section 6.32.8.)
