Constants

Home, Up: Operators and Constants

Hypatia knows the following constants:

PI, TAU (PI times 2), E (Euler's number), and PHI (the "golden ratio").

User-defined constants will be discussed in the context of variables.

Values of Hypatia's Constants

PI = 3.141592653589793238

TAU = 6.28318530717958648

E = 2.718281828459045235

PHI = 1.618033988749894848

While floating point numbers are shown with up to 15 significant digits, Hypatia's internal accuracy is somewhat higher. Constants are defined with 19 digits to reduce rounding errors of calculation results as far as possible.
