OM-53B
All function arguments need
parentheses.
LEFT$(string,length)
RIGHT$(string$,length)
MID$(string,start,length), length defaults to rest of string.
MID$(start,length)
Works only with the special string variable $.
Length defaults to rest of string.
795P: $="expr"
MODE 20,V
Round to d decimal places.
Examples round to cents.
Workarounds for positive x only!
RND(x,-d – 1), RND(X,-3)
ROUND(x,-d – 1), ROUND(X,-3)
Display only: PRINT USING "###.##";X
Works for current line only.
Display only: SET Fd, SET Ed set
display precision
Display only: PRINT USING "###.##";X
Works for current line only.
Symbol π
Power x
y
x y (special symbol)↑
<, ≤, >, ≥, =, ≠ (special symbols)
Low. Manual recommends
parentheses.
HEX$(n), n<2
16
, result is padded with "0" to four hex digits.
DEG(d,m,s) DEG(d,m,s)
d / 180 * π
r / π * 180
PRC r,θ -> x=X,y=Y x=r * COS θ, y=r * SIN θ REC(r,θ) -> X,Y REC(r,θ) -> x=X, y=Y
RPC x,y -> r=X,θ=Y
Commands
r=SQR(x*x + y*y)
θ=ACS(x / r)
POL(x,y) -> X,Y
See FX-850P.
POL(x,y) -> r=X, θ=Y
Both functions return variable X.
