UKismetMathLibrary::DegTan
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticBlueprintPureUFUNCTION
Description
Returns the tangent of angle A where A is in degrees. Use this instead of FMath::Tan when your angle is already in degrees to avoid manually converting.
Caveats & Gotchas
- • Tangent is undefined at ±90 degrees and returns a very large (near-infinite) value — guard against those inputs if they can occur in your data.
- • Unlike the radian-based FMath::Tan, this function handles the degree-to-radian conversion internally, so passing a radian value will produce incorrect results.
