FADD

Adds two floating point numbers.

Synopsis

FADD(num1,num2)

Arguments

num An expression that resolves to a numeric value.

Description

The FADD function adds two numbers and returns the result. If a num value is a null string or a non-numeric value, FADD parses its value as 0 (zero).

You can perform the same operation using the addition operator (+). Refer to the Operators page of this manual.

Arithmetic Operations

  • To perform arithmetic operations on floating point numbers, use the FADD, FSUB, FMUL, and FDIV functions, or use the standard arithmetic operators.

  • To perform arithmetic operations on numeric strings, use the SADD, SSUB, SMUL, and SDIV functions.

  • To perform integer division, use the DIV function. To perform modulo division, use the MOD function.

  • To perform arithmetic operations on corresponding elements of dynamic arrays, use the ADDS, SUBS, MULS, DIVS, and MODS functions.

  • To add together the element values within a single dynamic array, use either the SUM function (for single-level dynamic arrays) or the SUMMATION function (for multi-level dynamic arrays).

  • To perform numeric comparison operations, use the SCMP function, or use the standard comparison operators.

Examples

The following example uses the FADD function to add two floating point numbers:

a=11.95
b=10.25
PRINT FADD(a,b);  ! returns 22.2
