Val function as used to convert a string to a numeric value

for example, let str be a string,

Dim str as string

Dim int as integer

str="09090"

int=val(str)

gives int = 9090

also, used to extract the numeric part out of a following string,

ie. a=val("98ASR_tyui") would give a=98

however,

b=val("The89")
