ROOT (Root)
Valid Operands
For the valid operand number range, see page 6-2.
Since the ROOT instruction is executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction
should be used as required.
Valid Data Types
When a word operand such as D (data register) or L (link register) is designated as the source or destination, 1 point (word
data type) is used.
Examples: ROOT
Operand Function I Q M R T C D L Constant Repeat
S1 (Source 1) Binary data ——————XX X —
D1 (Destination 1) Destination to store results —————— XX ——
W (word) I (integer) D (double word) L (long)
X ———
When input is on, the square root of operand designated by S1 is extracted and
is stored to the destination designated by D1.
Valid values are 0 to 65535. The square root is calculated to two decimals,
omitting the figures below the second place of decimals.
