F# for Quantitative Finance

Learning about arithmetic comparisons

Arithmetic comparisons are used to compare two numbers for relationships. It's good to know all the operators that are shown in the following table:

Operator	Example	Description
<	x < y	Less than
<=	x <= y	Less than or equal to
>	x > y	Greater than
>=	x >= y	Greater than or equal to
(=)	x = y	Equality
<>	x <> y	Inequality
min	min x y	Minimum
max	max x y	Maximum

Some examples of arithmetic comparisons are as follows:

> 5.0 = 5.0;;
val it : bool = true
> 1 < 4;;
val it : bool = true
> 1.0 > 3.0;;
val it : bool = false

It is also worth noticing that you can't compare numbers of different types in F#. To do this, you have to convert one of them as follows:

> 5.0 >= 10;; 5.0 >= 10 -------^^ ...
