Hi Jb,
I know what u mean now. What u mentioned below "var pi = Math.PI" is a local
variable declaration. I would be able to see the following if I used it as a
variable declaration, but what I meant is I want a field declaration.
ldc.r8 3.1415926535897931
stloc pi
Field declaration eg: "public double pi = Math.PI;"
But I can only detect this field when I assign this value to the field in a
method.
If I put it as a field declaration or assign this value to the field in a
ctr, I won't be able to see the above instr.
Is there anyway I can see it even if I put it as a field declaration or
overwrite the field in a ctr?
Hope to hear a reply from you, thanks.
Li Yen

But how has it got to do with me not being able to detect the field
PIValue
as written and Math.PI as read?
Again, if you had bothered to investigate a little bit you would know.
PI is defined as a constant, so the compiler will inline its value
everywhere it's used
var pi = Math.PI is compiled as:
ldc.r8 3.1415926535897931
stloc pi
So if you want to detect where PI is used, you have to check for the
`ldc.r8 Math.PI` pattern.
