DispartReal
The DispartReal instruction separates a real number into the signed mantissa and the exponent.
*1 If you omit the input parameter, the default value is not applied. A building error will occur.
*2 The valid ranges depend on the data types of In and Fraction. Refer to Function for details.
*3 If In is REAL data, −44 to 32. If In is LREAL data, −322 to 294
The DispartReal instruction separates real number In into signed mantissa Fraction and exponent
Exponent.
If In is REAL data, Fraction is a 7-digit integer. If In is LREAL data, Fraction is a 15-digit integer.
