If you want to convert strings of hexadecimal (0xa), octal (0755),
binary (0b) to integers, you can use unary + operator.
:echo +'0xa'
=> 10
:echo +'0755'
=> 493
:echo
Hexadecimal (not octal) seems to be a special case:
:echo str2float('0x1') str2float('0xff') str2float('010') str2float('0b1')
answers
1.0 255.0 10.0 0.0
while
:echo 0x1 0xff 010 0b1
answers
1 255 8 1
Not yet sure if I'll call it a feature or a bug.
Best regards,
Tony.

See help for str2float() - all "text after the number is silently ignored"
for the second case.
See help in the Variables section 1.1, under the section for conversion.
For the first case; octal conversion happened in the first case before
applying the str2float().

str2float('0x1') returns 1 ( as expected )
but
str2float('0b1') returns 0 ( why ? )
