We use the generic type name \fBgentype\fR to indicate that the function can take \fBint\fR, \fBint2\fR, \fBint3\fR, \fBint4\fR, \fBint8\fR, \fBint16\fR, \fBuint\fR, \fBuint2\fR, \fBuint4\fR, \fBuint8\fR, or \fBuint16\fR as the type for the arguments\&. .SH "SPECIFICATION" .PP \m[blue]\fBOpenCL Specification\fR\m[]\&\s-2\u[1]\d\s+2 .SH "SEE ALSO" .PP \fBintegerFunctions\fR(3clc) .SH "AUTHORS" .PP \fBThe Khronos Group\fR .SH "COPYRIGHT" .br Copyright \(co 2007-2011 The Khronos Group Inc. .br Permission is hereby granted, free of charge, to any person obtaining a copy of this software and/or associated documentation files (the "Materials"), to deal in the Materials without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Materials, and to permit persons to whom the Materials are furnished to do so, subject to the condition that this copyright notice and permission notice shall be included in all copies or substantial portions of the Materials. .sp .SH "NOTES" .IP " 1." 4 OpenCL Specification .RS 4 \%page 256, section 6.12.3 - Integer Functions .RE
