Is there a way to let lua 5.1.4 support data type(UInt32/Int64/UInt64)

["陶陶" <taozuhong@...>]

Hi all,

 

I have met a trouble about big integer(UInt32/Int64/UInt64), the detail as follow:

I use tolua++ encapsulation c++ class to lua script, but it lost the data(just 0 or -1), because lua use double store all numeric data in default.

 

Is there a way to let lua 5.1.4 support data type(UInt32/Int64/UInt64),  could some guys can give me some example code?

 

thanks in advanced.

 

the follow is found in msdn:

The double type contains 64 bits: 1 for sign, 11 for the exponent, and 52 for the mantissa. Its range is +/–1.7E308 with at least 15 digits of precision.

long long(Int64): 1 for sign, 63 for numeric value
unsigned long long(UInt64): 64 for numeric value
