Regular Expression: Non negative real

[yrwyddfa]

I'm stumped.

Can anyone give me the regular expression for testing a string to see if it's a non negative real?

ie

0.000 F
0.001 T
0.101 T
1.000 T
1.111 T

There is no fixed length to the decimal part, either.

Many thanks,

M

If csng(field) > 0 then
endif

If csng(field) > 0 then
endif

Thanks for the quick reply, but that's not a regular expression.

For instance, a non-negative integer can be matched using '^-{0}[0-9]+$' which denotes the set of integers 0,1,2,3,4 . . .n

Just add a decimal point and any number of integers, in that order, to the right end. I'm a bit rusty at Regex, but I think it would be ^-{0}d+\.d+$

Thanks.

The '^-{0}\d+\.\d+$' expression does evaluate reals, but does not exclude 0.0
