The first 100 digits of pi (π) are: 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679. Pi is an irrational number, meaning it has an infinite number of non-repeating digits beyond the decimal point. In the movie "Pi," directed by Darren Aronofsky, the protagonist, Max Cohen, becomes obsessed with finding patterns in the digits of pi, reflecting themes of obsession and the search for meaning.

In the movie "Pi," directed by Darren Aronofsky, the symbol π represents the mathematical constant pi, which is the ratio of a circle's circumference to its diameter, approximately equal to 3.14159. However, more than just a mathematical concept, pi symbolizes the search for order and patterns in the chaos of life. The protagonist, Max Cohen, is obsessed with discovering a universal numerical pattern that governs the universe, reflecting themes of obsession, madness, and the intersection of mathematics and mysticism.

In the context of an oximeter, "pi%" refers to the perfusion index, which measures the strength of blood flow at the sensor site. A normal perfusion index typically ranges from 0.02% to 20%. However, values can vary based on individual factors such as circulation and the site of measurement. A higher perfusion index indicates better blood flow, while a lower value may suggest poor circulation or other issues. It's important to consult medical professionals for interpretation of oximeter readings in relation to overall health.
