Integers from excel files become floats?

Question

I use xlrd to read data from excel files.

For integers stored in the files, let\'s say 63, the xlrd interprets it as 63.

Answer 1

Excel treats all numbers as floats. In general, it doesn't care whether your_number % 1 == 0.0 is true or not.

Example: A1 = 63.0, B1 = 63, C1 = INT(A1), A2 = TYPE(A1), B2 = TYPE(B1), C2 = TYPE(C1) You'l see that TYPE() returns 1 in each case.

From the Excel Help:

If value is   TYPE returns 
Number        1 
Text          2 
Logical value 4 
Error value   16 
Array         64 

xlrd reports what it finds. xlrd doesn't mangle its input before exposing it to you. Converting a column from (62.9, 63.0, 63.1, etc) to (62.9, 63, 63.1, etc) would seem like a pointless waste of CPU time to me.
