Request for help on math_format function

[Charles Seman]

Robert,

Here are some results from a script constructed following your code
(attached):

ga-> test_math_format.gs
math_format("%02.0g",5) = 05
math_format("%02.1g",5) = 05
math_format("%02.2g",5) = 05
math_format("%2.0g",5) =  5
math_format("%03.2d",5) =  00
math_format("%02.0g",5.0) = 05
math_format("%02.1g",5.0) = 05
math_format("%03.1g",5.0) = 005
math_format("%03.2d",5.0) =  00
math_format("%02.0g",5.1) = 05
math_format("%02.1g",5.1) = 05
math_format("%02.0f",5.1) = 05
math_format("%02.1f",5.1) = 5.1
math_format("%02.2f",5.1) = 5.10
math_format("%2.2f",5.1) = 5.10
math_format("%03.2f",5.1) = 5.10
math_format("%03.2d",5.1) = 1717986918
math_format("%02.2d",5.1) = 1717986918
math_format("%02.0d",5.1) = 1717986918

I hope this helps,
Chuck
