function Is-Numeric ($Value) issue in client.ps1 #86

Closed lonestep closed 7 years ago

lonestep commented 8 years ago

function Is-Numeric ($Value) { return $Value -match "^[\d.]+$" }

We have a version string like: 11.2.0.2888 It's been judged as "Int32" and lead to an exception, the cause is this function "Is-Numeric"

PS C:\ITSearch> Is-Numeric "1.2.3" True PS C:\ITSearch> Is-Numeric 5e3 False

my suggestion is:

function Is-Numeric ($Value) { try{ (Invoke-Expression $Value).GetType().Name -match 'byte|short|int32|long|sbyte|ushort|uint32|ulong|float|double|decimal' } catch{ return $false} }

OR simply : $Value -match "^[\d]+\.*[\d]*$"
