Supplied Functions (numeric general)☆☆☆

ABS(x)　　　　The absolute value of x
SQR(x)　　　　The nonnegative square root of x
INT(x)　　　　The largest integer not greater than x
Example. INT(5.4)=5, INT(5)=5, INT(-4.4)=-5
MOD(x,y)　　　x-y*INT(x/y) 　x modulo y
Example. MOD(5,3)=2, MOD(-5,3)=1, MOD(3.14,1)=0.14
ROUND(x,n)　　INT(x*10^n+0.5)/10^n 　The value of x rounded to n digits of decimal place
CEIL(x)　　　 -INT(-x) 　The smallest integer not less than x
Example.　CEIL(5.4)=6, CEIL(5)=5, CEIL(-4.4)=-4
SGN(x)　　　　the sign of x
SGN(x)=1 if x>0,
SGN(0)=0,
SGN(x)=-1 if x<0
IP(x)　　　　 SGN(x)*INT(ABS(x)) 　The integer part of x
Example. IP(5.4)=5, IP(5)=5, IP(-4.4)=-4
FP(x)　　　　 x-IP(x) 　The fractional part of x
REMAINDER(x,y) x-y*IP(x/y)
Example. REMAINDER(5,3)=2, REMAINDER(-5,3)=-2
TRUNCATE(x,n)　IP(x*10^n)/10^n

<Note> SQR-functions can not be used on the RATIONAL operating mode, though INTSQR-functions can be used.
