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<boost::units::si::plane_angle, float>;
using degrees_f = boost::units::quantity<boost::units::degree::plane_angle, float>;
degrees_f to_degrees(const radians_f& angle) { return static_cast<degrees_f>(angle); }
radians_f to_radians(const degrees_f& angle) { return static_cast<radians_f>(angle); }
===
cvtss2sd - Converts a single-precision floating-point value in the “convert-from” source operand to a double-precision floating-point value in 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.

Carel
