7.2 Additional Builtins for Numeric Operations ¶

GCC provides a large set of built-in functions for operating on GCC’s extended set of floating-point and integer types (see Additional Numeric Types). The floating-point builtins include functions for building and testing infinities and NaNs. On integer types, there are additional bit manipulation functions, byte-swapping, and CRC functions.

Many of these builtins are type-generic and can operate on any floating-point or integer operand.

• Floating-Point Format Builtins
• Bit Operation Builtins
• Byte-Swapping Builtins
• CRC Builtins
• Built-in Functions to Perform Arithmetic with Overflow Checking
