Subject: Calc; calc-simplify-units not working as documented for trigometric functions
Date: Fri, 01 Jul 2016 16:31:30 -0700 [thread overview]
Message-ID: <lz8txlx7e5.fsf@hamburg.de> (raw)
In Calc do
'sin(45 deg)
u s
Result: 0.0137073546047
Expected result: 0.707106781187
The actual result equals to sin(pi/4) in deg mode whereas the expected
result of "the sine of 45 degrees" is the one documented in
"info:Calc#Trigonometric and HyperbolicFunctions".
The same applies for other trigonometric functions and for other values
of 45 or the 'deg' unit (i.e. 'rad or 'grad').
