Numeric Calc
GCD GCD(,)
Obtains the greatest common divisor of multiple integers.
Syntax: GCD( n , m )
LCM LCM(,)
Obtains the least common multiple of multiple integers.
Syntax: LCM( n , m )
Absolute Value Abs()
Finds the absolute value of argument n .
Syntax: | n | Abs( n )
Integer Part Int()
Extracts the integer part of argument n .
Syntax: Int( n )
Example: Int(-3.5) = -3
Fraction Part Frac()
Extracts the fractional part of argument n .
Syntax: Frac( n )
Example: Frac(-3.5) = -0.5
Round Off Rnd
This function is available on the Calculation tab of the Calculate app. It rounds the value of the last calculation
result (Ans) on the result display in accordance with the S > [Display] setting.
Syntax: Rnd (no argument, valid for previous calculation result only)
Example: While [Display] > [Fix3: 0.123], to divide 10 by 3 and then multiply Ans by 3
Rnd not used:
Rnd used:
• When the setting is [Display] > [Fix3: 0.123], 10÷3=3.333 is displayed, but 15 digits is retained internally, so
Ans×3=10.000. If the result of 10÷3 is rounded using Rnd as shown, Ans×3=9.999.
Largest Integer Intg()
Returns the largest integer that does not exceed argument n .
Syntax: Intg( n )
Example: Intg(-10.56) = -11
Round Internal RndFix()
Rounds argument n to the place following the number of decimal places specified by m (0 to 9).
Syntax: RndFix( n [, m ])
• If m is omitted, rounding is performed in accordance with the S > [Display] setting, the same as with the
Rnd function.
Not allowed within this syntax: d/dx, d
Example: RndFix(1.23456,3) = 1.235
Division Remainder MOD(,)
This function obtains the remainder of a division operation. It returns the remainder when n is divided by m .
Syntax: MOD( n , m ) ( n , m = integers)
