Well, when you read the description of QPI, it is described:

Quote:HP Prime port of QPI 4.3 (originally for the HP 48 series). Approximates any floating point numbers by a rational number, square root, multiple of PI, exponential or a logarithm depending on which approximation seems best.
By Han Duong (HPSolo) and Mika Heiskanen.

Since any number can be divided by 1, they are all rational numbers. If you don't care for:

fp2rat(); <== pretty self explanatory

how about:

fp2a(); <== a little vague
fp2apr(); <== too long
