# Type conversion

Perform element-wise floating-point to integer and integer to floating-point conversion.

## Topics

### Conversion between floating-point types

The functions in this group convert between single-precision and double-precision floating-point vectors.

[`doubleToFloat(_:)`](/documentation/Accelerate/vDSP/doubleToFloat(_:))

Returns single-precision values converted from a double-precision source.

[`floatToDouble(_:)`](/documentation/Accelerate/vDSP/floatToDouble(_:))

Returns double-precision values converted from a single-precision source.

[`convertElements(of:to:)`](/documentation/Accelerate/vDSP/convertElements(of:to:)-2ejgr)

Converts single-precision values to double-precision values.

[`convertElements(of:to:)`](/documentation/Accelerate/vDSP/convertElements(of:to:)-698ye)

Converts double-precision values to single-precision values.

[`vDSP_vspdp`](/documentation/Accelerate/vDSP_vspdp)

Converts a single-precision vector to a double-precision vector.

[`vDSP_vdpsp`](/documentation/Accelerate/vDSP_vdpsp)

Converts a double-precision vector to a single-precision vector.
