QUESTION
The max values of int, float and long in Scala are:
Int.MaxValue = 2147483647
Float.MaxValue = 3.4028235E38
Long.MaxValue = 9223372036854775807L
From the authors of Scala compiler, Keynote, PNW Scala 2013, slide 16 What's Int.MaxValue between friends?

Answered 2017-Apr-26 at 19:03A Float
is a 4-byte floating point value. Meanwhile a Long
is an 8-byte value and an Int
is also a 4-byte value. However, the way numbers are stored in 4-byte floating point values means that they have only around 8 digits of precision. Consequently, they do not have the capacity to store even the 4 most significant bytes (around 9-10 digits) of a Long regardless of the value of the least 4 significant bytes (another 9-10 digits).
Consequently, the Float
representation of the two expressions is the same, because the bits that differ are below the resolution of a Float
. Hence the two values compare equal.
QUESTION
Context: I've been using Extempore and Opusmodus to do computer assisted composition in live situations (programming classical music in front of audiences). Since I'm a professional .Net developer, I started writing my own software for .Net (combi of F# and C#) heavily influenced by both Extempore and Opusmodus. I now come to the point of implementing Temporal Recursion as it works in Extempore and can't find a way to do that on the .Net platform. Some directions and inspiration would be very helpful.
Definition: A temporal recursion is most simply defined as any block of code (function, method, etc..) that schedules itself to be called back at some precise future point in time.
Examples in Scheme: In theory a standard recursive function is a temporally recursive function that calls itself back immediately - i.e. without any temporal delay. For example (in Scheme):

But then I thought that maybe you don't need "general", maybe you just have one-two functions like this (i.e. "chords" and "percussion", that's it?). If that is the case, you may be satisfied with just keeping function references as mutable variables:
