inline - f# idiomatic type resolution solution for resolving to the wrong type -

i'm getting started f# have code analogous following:

let square x = x*x  let result = square 5.1  let result' = square 12 

unfortunately, results in following error: this expression expected have type float here has type int

is there idiomatic f# solution problem, or thinking being tainted c# experience?

just write that:

let inline square x = x * x 

otherwise, after first time used square function, type inferred float -> float. hence, , given f# not automatic conversion int float, receive error.

so, if don't want use inline, simplest solution write

 let result' = square (float 12) 

it simple , yet readable.

for more advanced solutions please take @ this: does f# have generic arithmetic support?

but solutions (imho) incomprehensible.
