ACOS

Top  Previous  Next

 

The ACOS of accu 1 is calculated and stored in accu 1 in radiant.

 

It is important that the operand in accu 1 is already in the REAL-format. If it is loaded as Int or DInt it will have to be changed into a REAL-number with DTR before calculating. If an operand that is loaded as Int can be negative it will also have to be extended to the Dword-format with ITD before.

 

ACOS(1)

= 0

ACOS(0)

= Pi / 2 ( Pi = 3,141592...)

ACOS(-1)

= Pi  ( Pi = 3,141592...)
