Put32Float Function

Overview

The Put32Float function puts a 32-bit floating to a buffer at a specified byte position.

Syntax/Parameters

Syntax

int = Put32Float ( buffer data, int position, float value );

Parameters

data

A buffer as bytes, chars, string or a handle to a Data Object. This is referenced on a byte by byte position to write four bytes to create the 32-bit floating-point value.

position

An int specifying a zero-based position in bytes. This should point to the start of the data for the float. If the position plus the size of the data element is outside of the scope of the buffer, a range error will be returned.

value

A float value to place in the buffer. The value will be converted from a 64-bit to a 32-bit float thus loosing precision.

Return Value

Returns an int as ERROR_NONE or a formatted error code on failure.

Remarks

The Put32Float function allows a script to reach into a buffer and place a 32-bit floating-point value. Note that float value is internally converted from a 64-bit to 32-bit floating point number which will result in lose of precision and can lead to values that are out of range.

When adding to a single-dimension array, the axis depth is adjusted if the placement exceeds the last position. For other types or multiple dimensions, the axis depth is not adjusted. For automatically allocated arrays, the array size is not adjusted using this function. Any fraction amount of the data type size will push the depth plus one element.

The last position of the Data Object is also adjusted if the end position if the size of the value placed exceeds the last position.
