Hypercalc is a Perl program written by Robert Munafo[1] that is designed to manipulate very large numbers by storing them in a notation called "PT vectors," in which \(a \text{PT} b = \underbrace{10^{10^{10^{.^{.^{.^{b}}}}}}}_a\). "PT" stands for "Powers of Ten."[2] It is licensed under the GNU General Public License, and operates through a terminal interface.

Kenny Chan created an online version[3] by porting the program to JavaScript.

The method Hypercalc uses to store its large numbers makes it susceptible to the power-tower paradox.
