Performing Floating Point Calculation |
| 【EXPLANATION】 |
The Floating point calculation is performed in FLOAT command.
A=expr. Expr is performed as Floating point calculation. When storethe value into A, It converts the value an Integer.
FP(n)=expr. Expr is performed as Floating point calculation, It stores the value into FP(n) as it is.
In the FLOAT command the functions:SIN,COS,TAN,ATAN,ACOS,SQR、RAD,DEG,VAL,etc works as double precision functions.

' Get Pie
FLOAT FP(6)=ACOS(SQR(3)/2)*6
FLOAT FP(6)=(FP(6)-3)*10
PRINT "PIE=3." FP(10000,6)
' Get Napier
a=1
FLOAT FP(2)=1
FOR i=1 TO 100
a=a*i
FLOAT FP(2)=FP(2)+1/a
NEXT
FLOAT FP(2)=(FP(2)-2)*10
PRINT "Napier=2." FP(10000,2)
'
PRINT "Second order equation X*X+4*X+3"
a=1 : b=4 : c=3
FLOAT FP(0)=(SQR(b*b-(4*a*c))-b)/2/a
FLOAT FP(1)=(SQR(b*b-(4*a*c))*-1-b)/2/a
PRINT FP(10000,0) FP(10000,1)
