testing if variable contains number

[rodrigo_sjc_sp]

Sorry. the title is wrong, is if the variable is numeric!

 

 

 

What better way to test if a variable is numeric .......

 

 

Ex:

 

variable x = 100

x is numberic

 

variable x = B

x is not numberic

See post 4 in this thread.

(numberp x)

 

-David

[pBe]

(numberp x)

 

-David

 

X2

 

And if by chance said variable is not a real nor an integer i.e x = "100"

 

(or (numberp s)
	     (numberp (read s)))

This is more specific to check if the variable is REAL or INTEGER ( according to your example )
