11 INSTRUCTIONS AND FUNCTIONS
MKSMBF$
Function
• Converts data of floating point real numbers used by the AnA/AnU/AnUSCPU (IEEE format
single-precision internal expression) into a character string that can be converted to a
numeric value using the CVS function.
MKSMBF$ ( <numeric expression> )
Syntax
numeric expression
A!=CVS(MKSMBF$(B!))
Examples
• The MKSMBF$ function converts data of floating point real numbers used by the
Description
AnA/AnU/AnUSCPU (IEEE format single-precision internal expression) into a character
string that can be converted to a numeric value using the CVS function in AD51H-BASIC.
• The AnA/AnU/AnUSCPU internal expression (IEEE format single-precision internal
expression) and the AD51H-BASIC internal expression for real numbers are different. The
MKSMBF$ function converts between the two.
• Be sure to specify a numeric value of AnA/AnU/AnUSCPU internal expression (IEEE
format single-precision internal expression) for the <numeric expression>. Conversion will
not be performed correctly with other numeric values.
• The MKSMBF$ function only performs data conversion for single-precision real numbers.
• When reading an AnA/AnU/AnUSCPU floating point real number with the PCRD
instruction, store the data in integer arrays. Then assign the data to a single-precision real
number variable, and then convert with the MKSMBF$ function.
PCRD Instruction
AnA/AnU/AnUSCPU
• Other than converting AnA/AnU/AnUSCPU floating point data, the MKSMBF$ function is
used, for example, to convert system data that performs internal expression of IEEE
format single-precision numeric values.
