.SH CAVEATS
Due to precision constraints and the way floats are represented in accordance
with the IEEE Standard for Floating Point Arithmetic (\fIIEEE 754\fP),
floating-point arithmetic has rounding errors. This is somewhat curbed by using
the machine epsilon as provided by the Rust standard library to which to round
numbers. Because of this, variation is expected in the number of decimal places
the program can handle based on the platform and hardware of any given machine.
