--- Comment #7 from Tony Reix <tony.reix at atos dot net> --- (In reply to Andreas Schwab from comment #1) > Converting a negative float to an unsigned integer is undefined. http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1256.pdf says (page 43): If the value of the integral part cannot be represented by the integer type, the behavior is undefined.50) 50) The remaindering operation performed when a value of integer type is converted to unsigned type need not be performed when a value of real floating type is converted to unsigned type. Thus, the range of portable real floating values is (−1, Utype_MAX+1). Hummmmmmm
