FUNCTIONUnder review
Mathc
MathC(cNum1,cOperacao,cNum2) -> cResultPerforms arithmetic on numbers represented as strings.
Overview
MathC takes two text numbers and an operator: +, -, *, / or e for exponentiation. Its return is also text; documentation mentions up to 18 digits of precision. This is not the Match pattern-comparison function. Converting the result with Val may lose properties of its text representation. (Sources: refs. 1–1.)
Syntax
MathC(cNum1,cOperacao,cNum2) -> cResultParameters
cOperacaoCharacterRequired
Arithmetic operator.
cNum2CharacterRequired
Second text number.
Return value
String containing the operation result.
