           Summary: Int32.Parse doesn't respect NumberStyles.AllowExponent
    Classification: Mono

Int32.Parse isn't correctly respecting NumberStyles.AllowExponent.  A cursory
glance at mcs/class/corlib/System/Int32.cs show that there's an intention to do
so, in 

internal static bool FindExponent (ref int pos, string s)

but this doesn't seem to be doing the trick.

Reproducible: Always

Steps to Reproduce:
int x = System.Int32.Parse("10249E+02",
System.Globalization.NumberStyles.AllowExponent,
System.Globalization.CultureInfo.InvariantCulture);

Actual Results:  
x == 10249

Expected Results:  
x == 1024900
