[Boost-users] boost units and single-precision floats

From compiler explorer I see the following assembly instructions: https://godbolt.org/z/Gnjr54dn6 cvtss2sd - Converts a single-precision floating-point value in the “convert-from” source operand to a double-precision floating-point value in

Hi, I have aliases for radians and degrees that use float as the storage type. When I convert between these two units I see the assembly promote the values to doubles and then back to floats. How can I make sure that all operations and conversions stay in floats? PS: I would not be surprised if I have defined my aliases or/and my conversion functions incorrectly. My Code: === using radians_f = boost::units::quantity; using degrees_f = boost::units::quantity; degrees_f to_degrees(const radians_f& angle) { return static_cast(angle); } radians_f to_radians(const degrees_f& angle) { return static_cast(angle); } === the destination operand. mulsd - Multiplies the low double-precision floating-point value in the second source operand by the low double-precision floating-point value in the first source operand. cvtsd2ss - Converts a double-precision floating-point value in the “convert-from” source operand to a single-precision floating-point value Any help will be appreciated.
