[lp_integer_toUnsigned]

Description

Returns the base10 unsigned integer value given a signed base10 integer.  The octet remains unchanged, only the decimal representation is converted.

Requires [lp_integer_bits], [lp_math_dectobin]

Sample Usage

lp_integer_toUnsigned: -93; // returns 163
'
';
lp_integer_toUnsigned: -1; // returns 255
'
';
lp_integer_toUnsigned: -128; // returns 128
