Module num 

Explicit numeric conversions used at UI/model boundaries.

Keeping the necessarily lossy casts here makes their policy consistent: integer narrowing and signed-to-unsigned conversions saturate instead of wrapping, while geometry conversions use Rust’s saturating float-to-int semantics. Call sites stay readable without scattering lint exceptions.

Functions

decimal_places

How many decimal places value is written with at its shortest (0.25 has two, 3.0 none); None when it is not finite or needs more places than snap_decimal can keep exact.

snap_decimal

value, a sum of operands or of whole multiples of them, as the decimal those operands make: rounded to the most places any of them is written with. Binary floats drift where decimals do not (0.1 + 0.2 is 0.30000000000000004, 7 × 0.1 is 0.7000000000000001), so a stepper or slider moved in tenths would otherwise land beside the value it shows and miss the end of its range. value is returned unchanged when an operand is not a short decimal.
