SMUL

Multiplies two numeric strings.

Synopsis

SMUL(numstr1,numstr2)

Arguments

numstr An expression that resolves to a number or numeric string.

Description

The SMUL function multiplies the value of two numeric strings and returns a numeric value. If a numstr value is the null string or a non-numeric value, SMUL parses its value as 0 (zero).

Arithmetic Operations

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

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

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