3.2. The VFP extension

The VFP extension performs single-precision and double-precision floating-point operations, and some half-precision operations.

There are build options to implement a single-precision FPU or a double-precision FPU. See Chapter 5 Floating Point Unit Programmers Model for implementation-specific information.

See the ARM® Architecture Reference Manual ARMv7-A and ARMv7-R edition for more information about the VFP extension.
