X2Frac

You can use the X2Frac function to convert an Extended number to a Fract number.

FUNCTION X2Frac (x: Extended): Fract;

x

The Extended number to be converted to a Fract number.

DESCRIPTION

The X2Frac function returns the best Fract approximation of the Extended number you supply in the x parameter. If x is greater than the maximum representable Fract number, the X2Frac function returns $7FFFFFFF. If x is less than the negative number with the highest absolute value, X2Frac returns $80000000.
