constexpr TO ChimeraTK::numeric::convert ( FROM  value )

constexpr

Convert numeric data types with proper rounding and clamping to the target value range.

The exact behaviour is defined as follows:

• integer target types: both positive and negative overflows clamp to the closest value of the target type.
• unsigned integer targets: negative input values give always 0
• double-to-single floats: overflows clamp, Inf and NaN is kept as is
• float-to-integer: rounding to nearest integer
• bool targets: any non-zero value (after rounding to nearest integer) is true (also negative values)
